3% in UC and 3.6% in CD patients.70 Pediatric Inflammatory Bowel Diseases There were two reports available on pediatric IBDs in Iran: one a hospital-based study and the other a retrospective study.21,71 The former underlined pancolitis as the most common involved site (69.6%) in UC on colonoscopy and reported a higher M/F ratio in both UC (0.6/0.4) and CD (0.58/0.42) Inhibitors,research,lifescience,medical patients. In the latter, the most common colonoscopic feature was erythema in UC and ulcer in CD. In a study conducted on Asian IBD pediatric patients in British Colombia in Canada,72 a pattern similar to

that of Iranian children vis-à-vis the M/F ratio (male predominance) was observed in both UC and CD patients. In addition, extensive Inhibitors,research,lifescience,medical colitis constituted the most frequent form of involvement in the patients. Table 4 depicts a comparison of the epidemiological data between Asian and Iranian IBD patients. Table 4 Comparison of epidemiological aspects of inflammatory bowel diseases between Asia and Iran Conclusion

The rate of IBDs has increased significantly in Asian countries during the last decade. The most important differences between Asia and Iran in Inhibitors,research,lifescience,medical regard to epidemiological aspects are in EIMs, family history, and NOD2/CARD15 mutation in CD patients and CTLA-4 gene polymorphism in UC patients. A precise, well-designed, multi-centric, population-based, prospective epidemiologic study must be performed in Asian countries, especially in Iran, in order to shed sufficient light on the incidence and prevalence of IBDs in this region.

Reactive airways dysfunction syndrome (RADS) is a non-immune mediated type of asthma-like disease characterized by Inhibitors,research,lifescience,medical the immediate onset of symptoms of cough, chest tightness, audible wheeze, and breathlessness after a toxic single exposure to an agent with irritating properties in the atmosphere in the form of dust, vapor, fume, or smoke.1 More than 30 different agents are known to cause RADS.2,3 The most common agents implicated in the causation of RADS include chlorine, toluene diisocyanate, and oxides of nitrogen.2 The Brazilian standard describes porcelain tile as any ceramic PDK4 tile made of clay, feldspar, and other inorganic raw materials that is either pressed or extruded and contains water absorption of less than 0.5%. However, porcelain tile dust as a cause of RADS has not been previously reported. We present a 45-year-old male laborer with an acute onset of asthma after his first time heavy exposure to porcelain tile dust within 5 hours of exposure whose symptoms persisted for 5 months after the incident. To the best of our knowledge, this is the first reported case of RADS as a result of porcelain tile dust exposure.

” “Hoping against hope” is the tension between

” “Hoping against hope” is the tension between

hoping for a cure for their family member and the recognition that this is no longer a possibility. At the same time they had other types of hope. Hope for these participants was also a choice and a mindset. Many women wrote about how they tried their best, despite extremely discouraging circumstances, to look for hope each and every day in the simple things, and in focusing on the present. They chose to look for the positive aspects of each day and also resorted to good memories of the lives they had lived with the care Inhibitors,research,lifescience,medical selleck chemicals llc receiver. Choosing to be hopeful was not easy, and part of this mindset also involved acceptance of their circumstance, and striving to find a new ‘normal’ amidst so much uncertainty. The new normal and acceptance is described here by two participants: “Now we have adapted to the new normal. We are still optimistic… I guess we both know the odds are not in our favour but it is hard to do anything else but Inhibitors,research,lifescience,medical push into it and hope for the best.” “I know that we have changed our expectations of what is possible for our family and that’s ok. I think that my family has all adjusted to what our new “normal” is and we are trying

to embrace Inhibitors,research,lifescience,medical our opportunities right now.” Participants described several influences on their hope: temporal circumstances, social support, spirituality and faith. Circumstances The specific, temporal circumstances of each day could foster or take away from the participants’ hope. Caregivers’ levels of hope and their general mood were heavily dependent on the mood Inhibitors,research,lifescience,medical of the care recipient and the care receiver’s state of health. Good

days were more hopeful days. The weather and environment played a role in the caregivers’ perceptions of their hope, as one participant shared, “Hope, Inhibitors,research,lifescience,medical well it was hard to find any today except that the flowers are blooming beautifully, and that is something.” Factors that detracted from the participants’ hope were dreary weather, stressful travel and medical appointments, family conflict, and the declining health and well-being of the care receiver. One participant described her stress with driving and how she felt alone: “I feel alone even Ketanserin when people are here! Nobody really understands! [Care receiver] is sick. I need to lift him into the truck… I am scared of getting him into the truck tomorrow to go to [location of appointment].” Social support Social support was found to be a key theme that fosters hope, whether this was support from family members, friends or health professionals such as doctors and nurses. Many caregivers mentioned how celebrating an occasion with family members, seeing their grandchildren, having extra support from their sons and daughters or their siblings, brought hope to their day and to their lives, for example, “Our friends and our health team give me hope for tomorrow… my support if & when [care receiver] needs them or we need them.

Instead, several studies report a differential gene expression in

Instead, BMN 673 nmr several studies report a differential gene expression in cases versus controls in target areas of the brain for NRG1 and DTNBP1; given that associated alleles/haplotypes are located in introns, it can be suggested that the pathogenic mutations induce a regulatory dysfunction. The meaning of the variation of haplotypes across studies is currently not appropriately understood. Two Inhibitors,research,lifescience,medical putative interpretations are possible: Different “causal” mutations in the same gene contribute to the emergence of schizophrenia; these mutations are not yet known; different “causal” mutations

might predominate in different samples due to “genetic heterogeneity” of schizophrenia; significant associations Inhibitors,research,lifescience,medical to different haplotypes may be a consequence. Linkage disequilibrium between positional markers is variable across populations and samples; thus, the positional markers in linkage disequilibrium with the same “causal” mutations are different between populations and samples. It is currently not possible to decide which of both options Inhibitors,research,lifescience,medical is true. In any case, it is very unlikely that

the disparity between associated haplotypes of the gene reflects a “false positive” finding. Alternative successful strategies Two alternative strategies have also turned out to be successful: Cytogenic analyses in isolated families highly loaded with schizophrenia: A translocation was detected Inhibitors,research,lifescience,medical to cosegregate with the condition status in the family.6 A specific gene (not previously known) on chromosome 1 was regularly disrupted, and was named DISC1. Surprisingly, common mutations in this gene were also found to be associated Inhibitors,research,lifescience,medical with schizophrenia in outbred populations.7 Gene expression might guide to susceptibility genes: Given the plethora of differentially expressed genes in postmortem brains of patients with schizophrenia, specific hypotheses are required to sharpen the focus to differentially expressed

genes for further study. Assuming that synaptic and postsynaptic transmission is a crucial feature of schizophrenia, phosphokinases present as a family of candidate proteins; polymorphic genes coding for these units of intracellular signal transmission thus became “hot” candidate genes. These DNA-sequence (-)-p-Bromotetramisole Oxalate variants in the differentially expressed protein kinase B (AKT1) were found to be associated with schizophrenia.8 Several replications of the original finding have now been published.9 The detected susceptibility genes throw light on the etiology and the pathophysiology of schizophrenia. None of the abovementioned detected candidate genes has been implicated in the development of schizophrenia before.

Comparison of areas under the curve (AUC) was done with the method suggested by Hanley and McNeil.15) Time to first event analysis was performed using a Cox proportional hazards model with the combined endpoint of death, recurrence of PE and PE related hospital admission. To avoid overfitting of the model, we used a bootstrapping in that analysis. A p value less than 0.05 was considered statistically significant. Results Patient characteristics A total 50 consecutive patients (38 females, mean age 68 ± 14 years old) were included in this

study. Their baseline clinical and routine echocardiographic data are listed in Table 1. Common underlying Inhibitors,research,lifescience,medical etiologies were operations, malignancies and cerebrovascular accidents. In our study cohort, 9 had surgical treatments within 1 month. Five of them had orthopedic surgery of their lower extremities, 2 had abdominal surgeries, 1 had spinal surgery and 1 had flap surgery of her buttock. Six had malignancy; Inhibitors,research,lifescience,medical 2 stomach cancer, 1 pancreatic cancer, 1 renal cell carcinoma, 1 colon cancer and 1 bladder cancer. However, the underlying cause was not identified in about 42% of the patients. RV systolic dysfunction, defined by RVFAC less than 35%, was present in 39 patients (78%) and 17 patients (34%) underwent thrombolytic therapy. Of them, 2 had complications Inhibitors,research,lifescience,medical associated with thrombolytic therapy (1 minor bleeding and 1 major bleeding).

Table 1 Baseline characteristics (n = 50) Echocardiographic findings McConnell’s sign was found in 33 patients (66%). TAPSE and TASV showed significant correlation (r = 0.582, p < 0.001). TAPSE showed significant correlations with RVFAC (r Inhibitors,research,lifescience,medical = 0.841, p < 0.001), RV Tei index (r = -0.347, p = 0.018), pulmonary vascular resistance (PVR) (r = -0.635, p < 0.001) and LogBNP (r = -0.634, p < 0.001) (Fig. 1). TASV showed significant correlations with RVFAC (r = 0.605, p < 0.001), RV Tei index (r = -0.380, p = 0.009), PVR (r = -0.483, p = 0.001) and LogBNP (r = -0.477, p = 0.001) (Fig. 2). TAPSE showed

significant correlations with serum markers of RV dysfunction such as troponin-I level (r = -0.335, p = Inhibitors,research,lifescience,medical 0.019) and creatinine kinase-MB (CK-MB, r = -0.402, p = 0.005). However, TASV did not reveal the correlation with troponin I and CK-MB.

The increase in total vibration

The increase in total vibration energy in patients with REPE is likely caused by more significant airflow obstruction resulting in narrowed airways and more turbulence. Although airflow obstruction in the setting of pulmonary edema has long been acknowledged by clinicians [12], the mechanisms

responsible for this observation remain obscure. The elevation of pulmonary or bronchial vascular pressure likely results in reflex bronchoconstriction [13]. Other potential causes of airway narrowing include a geometric decrease in Inhibitors,research,lifescience,medical airway size from reduced lung volume, obstruction from intraluminal edema fluid, and bronchial mucosal swelling [13]. Some investigators [14,15], but not all [16], have found an increase in bronchial responsiveness to methacholine in patients with left ventricular dysfunction or mitral valve disease. The significance of this finding is not clear. Contrary to earlier reasoning, there is no evidence that engorged bronchovascular Inhibitors,research,lifescience,medical Selleck Afatinib bundles directly compress small airways [17-19]. CHF associated airway edema may also cause larger Inhibitors,research,lifescience,medical airways to be narrowed producing increased turbulence and noise [12-18]. The edema may additionally cause smaller airways to close and reopen during inspiration; thereby, increasing noise [19,21-23]. Therapies that reduce interstitial pulmonary edema and pleural effusion result in

reversal of the effects described above and would be expected to increase image area, as demonstrated in this Inhibitors,research,lifescience,medical investigation. Another manifestation of CHF is cardiomegaly. Since the pulmonary system and the heart share one thoracic space, an enlarged heart would decrease the space available for the lungs to expand [24-26]. This may be an additional explanation for the decreased vibration energy areas. Cardiomegaly may cause decreased lung volume particularly in the lower lung fields. In healthy volunteers, Inhibitors,research,lifescience,medical it has been shown that total vibration energy increases with increasing tidal volume [5]. Although the tidal volumes of the non-ventilated CHF patients in this study below were not measured, the decrease in vibration energy seen with treatment is

not likely due to decreased tidal volume because: 1) patients were instructed to take deep breaths for all recordings and larger volumes would be expected after clinical improvement [27] and 2) the increased work of breathing in CHF would likely cause respiratory muscle fatigue and shallow breathing (lower tidal volume) before therapy [28,29]. Nevertheless, to remove the confounding effects of tidal volume changes before and after clinical improvements, mechanically ventilated CHF patients were studied as a control group for same tidal volumes (not practical to quantitate tidal volume in the non-mechanically ventilated acutely dyspneic CHF patients), when REPE was present and again when the CHF had improved and REPE was reduced.

No specific guidance is given on whether or not patients with pr

No specific guidance is given on whether or not patients with pre-existing diabetes require closer monitoring; in these cases clinical judgement is often used. Recent studies have found an association between antipsychotic therapy and pneumonia. The link is better established in elderly patients with a possible dose-dependent IBET762 relationship and increased odds ratio

in those treated with atypical antipsychotics [Trifirò et al. 2010; Knol et al. 2008]. More specifically, in the adult population an association between fatal pneumonia and clozapine therapy is also suggested. In one study, pneumonia Inhibitors,research,lifescience,medical was found to be the primary cause of death in the majority of excess deaths seen in clozapine-treated patients [Taylor et al. 2009b]. The exact pathophysiological association between clozapine Inhibitors,research,lifescience,medical and pneumonia is unclear and it is important to note that this later study found that amongst the excess deaths, not one was found to have agranulocytosis at the time of death. Other possible mechanisms include aspiration pneumonia as a result of sialorrhea Inhibitors,research,lifescience,medical [Hinkes et al. 1996] or oesophageal dysfunction [Maddalena et al. 2004]; however, the exact process remains uncertain. Currently there is no formal guidance on monitoring

or early intervention for this complication in clozapine-treated patients. We present a case of a 43-year-old patient with schizoaffective disorder and pre-existing diabetes, who in the fourth week of clozapine therapy presented in a hyperglycaemic crisis and subsequently developed fatal pneumonia. We later discuss the clinical implications of safely monitoring

these rare but potentially fatal adverse Inhibitors,research,lifescience,medical effects. Case presentation Mr D was a 43-year-old patient of Afro-Caribbean origin, with an established diagnosis of schizoaffective disorder. He first became unwell aged 24 years and experienced numerous episodes of illness characterized by thought disorder, paranoid delusions Inhibitors,research,lifescience,medical and affective symptoms. These episodes were often associated with severe self neglect and aggression and required both voluntary and involuntary admissions to psychiatric wards for management. Despite often successful resolution of his symptoms with psychotropic management, Mr D was difficult to manage in the community because of poor compliance with medication, nonengagement with services and concomitant illicit drug use. In terms of function, he was able to live relatively GBA3 independently early on in his illness, however he required more support over time. His physical health was also of concern; he developed type 2 diabetes mellitus at the age of 41, had hypertension and a degree of chronic obstructive pulmonary disease (COPD), all of which required medical treatment. Contributory factors were morbid obesity, sedentary lifestyle, poor diet and heavy smoking. Approximately 18 months before his death, Mr D was admitted to an acute psychiatric ward as an involuntary patient following a relapse in his mental state.

Such data enable, for the first time, formulation of a quantitative, system-level view of immunity. With

such knowledge, the hope is to be able to identify comprehensively not only all components of an individual’s immune system, but a more narrow set of measurements (likely spanning multiple immune components) from which predictive metrics of immune health may be defined resulting in the Inhibitors,research,lifescience,medical actualization of clinical personalized medicine (Figure 3B). THE CLINICAL BENEFITS OF INCREASED RESOLUTION OF IMMUNE FUNCTION Historically, the ability to dissect biological phenomena with increased resolution has been closely tied not only to new discovery but to increased understanding of disease heterogeneity leading to improved detection Inhibitors,research,lifescience,medical and treatment outcomes. For medicine, the above-described technological innovations will primarily be judged by their ability to deliver clinically actionable information for improved diagnosis and treatment. The leap in resolution these technologies provide for each of the parts of the immune system surveyed is orders of magnitude higher than any technological or methodological progress to date. This is revealing Inhibitors,research,lifescience,medical striking variation even between antigen-specific single cells previously thought to be identical.5 It may be the case, and likely for the first time in immunology, that we have reached a level of learn more measurement accuracy Inhibitors,research,lifescience,medical that can capture the

noise of the immune system

itself. How the immune system handles noise to produce a robust response is likely a fascinating basic research question, but one less likely to be of clinical relevance, as such fluctuations are handled naturally by the system itself. If so, as in other fields of biology, delineating the natural noise from that which shows important functional differences would be of high relevance. Until then, the extent to which Inhibitors,research,lifescience,medical this spectacular resolution will be clinically actionable remains to be determined. Some of the first published studies using these advanced technologies suggest that clinically valuable information may be learned from increased resolution. The direct relevance of insights gained varies by assay type, the analyses performed with the generated data, and the appropriateness of the assay for probing the disease studied. Particularly strong evidence for clinical relevance has come from the results of phospho-flow, a technique first applied close to a only decade ago. Here studies have illustrated an ability to identify hyper-responsive cell subsets negatively prognostic of tumor progression,37 perform disease sub-classification based on signaling aberrations corresponding to clinical correlates,38 and understand drug mechanisms.9,39 With the arrival of mass cytometry, the power of phospho-flow analysis increases greatly as multiple signaling pathways can be profiled simultaneously and in all cells of the immune system.

Overall only 7 EGFR mutations were found among 347 pancreatic can

Overall only 7 EGFR mutations were found among 347 pancreatic cancers (2%). Kwak et al. demonstrated disease stabilization with EGFR inhibition (erlotinib with capecitabine) in 5 out of 55 cases, including both (2/2) pancreatic cancers with EGFR mutations (24). PIK3CA mutations were identified in 2 out of 56 cases (3.6%) of pancreatic adenocarcinoma. Jimeno et al. found that 2 of 10 human tumors were sensitive to EGFR inhibition, including the single (1/1) pancreatic cancer with PIK3CA mutation (30). Inhibitors,research,lifescience,medical Table 2 Summary

of publications investigating EGFR and PIK3CA mutations in pancreatic adenocarcinoma Similar search yielded eight articles and abstracts that investigated biliary tract carcinomas. The summary of these publications is presented in Table 3, including the results of this Selleck FDA approved Drug Library current study. A total of 19 EGFR mutations Inhibitors,research,lifescience,medical (10.5%) and 18 PIK3CA mutations (11.7%) were found in 180 and 154 biliary tumors, respectively. The latter percentage was influenced by the presence of PIK3CA mutations in one third of Chinese study population (8). Table 3 Summary of publications investigating EGFR and PIK3CA Mutations in Biliary Tract Carcinoma Discussion EGFR activation influences different intertwining signaling

pathways, including Ras/MAPK, phospholipase C, PI3K/Akt, signal transducer and activator of transcription, and Src/FAK pathways (43). EGFR is expressed by pancreatic tumor cells Inhibitors,research,lifescience,medical (7), and has been associated with lymph node involvement, metastasis and disease recurrence (44,45), and overall worse prognosis (46). High EGFR expression has been reported also in biliary cancer (8,9,47,48). Tan et al. demonstrated that

activation of EGFR is closely Inhibitors,research,lifescience,medical involved in cell dissociation in pancreatic cancer through activating MEK/ERK signaling pathway (49). Cytoplasmic Inhibitors,research,lifescience,medical overexpression of EGFR plays a significant role in the progression of pancreatic ductal adenocarcinoma, especially in the invasion and acquisition of aggressive clinical behavior (46). EGFR also contributes greatly to cholangiocarcinoma progression, associated with lymph node metastasis, aberrant p53 expression, proliferating activity, and carcinoma differentiation Endonuclease (50). EGFR is activated by bile acids and functions to induce COX-2 expression by an MAPK cascade that may contribute to progression of cholangiocarcinomas (51). Paez et al. searched for somatic genetic alterations in NSCLC specimens from Japan and the US by examining exons 2 through 25 of EGFR. They found missense and deletion mutations of EGFR in 13.4% of tumors, all within exons 18 through 21 of the kinase domain. The EGFR mutations were more frequent in adenocarcinomas, females, and Japanese patients (25% mutation prevalence vs. 1.6% in Americans) (4). The common EGFR mutations in NSCLC are exon 19 deletions and the L858R point mutation in exon 21 (52). PI3K activation has been shown to play an important role in cell survival signaling in a number of cell types (53).

191 In fact it is precisely its capacity for holistic processing

191 In fact it is precisely its capacity for holistic processing that enables the right JNK inhibitor molecular weight hemisphere to recognize individuals, since individuals are Gestalt, indivisible, wholes.159,186,192 In keeping with the principle that it is not what is done, but how it is done, that distinguishes the two hemispheres, one cannot

say that one hemisphere deals with single items (“units’”), and the other with “aggregates.” Inhibitors,research,lifescience,medical Both deal with “units” and both deal with “aggregates.” Thus, the right sees individual entities (its kind of units) in all their uniqueness, and it sees them as belonging in a contextual whole (its kind of aggregate), from which they are not divided. By contrast the left sees parts (its kind of units), which go to make up a something which it recognizes by the category to which it belongs (its kind of aggregate). However, the relationship between the smaller unit Inhibitors,research,lifescience,medical and the broader aggregate in either case is profoundly different: as is the mode of attention to the world with which it is associated. Where the left hemisphere is more concerned with abstract categories and types, the right hemisphere is more concerned with the uniqueness Inhibitors,research,lifescience,medical and individuality of each entity189,193,194 The right hemisphere’s role as what Ramachandran has described as the“anomaly detector” might in fact be seen rather as an aspect of its preference for things

as they actually exist (which are never entirely static or congruent – always changing, never the same) over abstract representation, in which things become fixed and equivalent, types rather than individuals. Where the left hemisphere utilizes abstract categories, the right hemisphere organizes experience according to specific exemplars.195-198 The left hemisphere takes an invariant or abstracted view in its representation Inhibitors,research,lifescience,medical of objects, where the right hemisphere uses stored “real world” views in order to group experience.195,199-200 The living versus the nonliving The Inhibitors,research,lifescience,medical left hemisphere

has more capacity for the abstract or impersonal, whereas, in keeping with its more contextualized view, the right hemisphere is less prone to abstraction, and prioritizes the personal.201,202 The left hemisphere tuclazepam is better at appreciating analytic or mechanical structures, whereas the right hemisphere is better adapted to an appreciation of wholes, such as living entities, that have not been put together from parts. The right hemisphere is more concerned with living individuals than manmade objects.203 The left hemisphere alone codes for nonliving things,204-207 while both hemispheres code for living things.206-208 However, at least one study has found a clean divide between the hemispheres, the left coding for the nonliving, and the right for the living, regardless of the task.209 The body image as a whole is a right-hemisphere entity, whereas body parts are the province of the left hemisphere.210 The left hemisphere codes for tools and machines.

Preparation of PEGylated Archaeosomes and PEGylated Liposomes Stock solutions of Egg-PC (1mg/mL) and PEG45-DSPE (1mg/mL) were prepared in CHCl3:CH3OH (2:1, v/v), while stock solutions Inhibitors,research,lifescience,medical of PEG45-Tetraether (1mg/mL) were prepared in CHCl3. Liposomes and

archaeosomes were obtained by the hydration method as already described elsewhere [16–18]. Briefly, the selected lipid solutions were mixed to yield either a CAL-101 clinical trial mixture of Egg-PC and PEG45-DSPE (90:10wt%) or a mixture of Egg-PC and PEG45-Tetraether (90:10wt%) with a total Inhibitors,research,lifescience,medical lipid concentration of 1mg/mL. The organic solvents were then evaporated using a rotary evaporator, and the lipid films thus obtained were dried under high vacuum for 2 hours at room temperature. The dried lipid films were then hydrated with 1mL of milliQ water. The solutions were vortexed and left at 4°C overnight. Archaeosome or liposome formulations

were sonicated at room temperature for two times 5min with interval of Inhibitors,research,lifescience,medical 5min using a Fischer scientific sonication bath (FB 15051) at 80KHz. Each formulation was realized in duplicate. 2.4. Encapsulation of Carboxyfluorescein into Inhibitors,research,lifescience,medical PEGylated Archaeosomes PEG45-Tetraether (90:10wt%) based archaeosomes and Egg-PC/PEG45-DSPE (90:10wt) PEGylated Liposomes: Carboxyfluorescein (CF) was encapsulated in Egg-PC based liposomes during the hydration phase as described elsewhere [19]. Briefly, Egg-PC/PEG45-Tetraether (90:10wt%) and Egg-PC/PEG45-DSPE (90:1wt%) lipid films were prepared as described above. After drying, both lipid films were hydrated with 1mL

of a tris(hydroxyl methyl) methylamine buffer (Tris buffer) at pH 7.4 containing CF at a concentration of 100mM. The solutions were vortexed and left at 4°C overnight. Both PEGylated archaeosomes and PEGylated Inhibitors,research,lifescience,medical liposomes containing CF were sonicated before (Fischer scientific sonication bath FB 15051-80KHz) at room temperature for two times 5min with interval of 5min. Nonencapsulated CF was eliminated by size exclusion column chromatography on the Sephadex G-50gel with the Tris buffer as eluent. Both PEGylated archaeosomes and PEGylated liposomes containing CF were analyzed by DLS and by fluorescence using a Fluoromax-3 (Horiba) spectrofluorimeter with excitation and emission wavelengths of 490 and 515nm, respectively. 2.5. Size, Polydispersity, and Zeta Potential Measurements The size (average diameter obtained by the cumulant result method), polydispersity and zeta potential of the formulations were measured by dynamic light scattering using a Delsa Nano Beckman Coulter apparatus at 25°C. The samples were diluted 2 times with milliQ water. 2.6.
