Palladium(II) Complexes Containing Mixed Nitrogen-Sulphur Donor Ligands: Interaction of [Pd(Methionine Methyl Ester)(H 2
Pd(MME)Cl2 complex (MME = methionine methyl ester) was synthesised and characterized by physicochemical measurements. The reaction of [Pd(MME)(H2O)2]2+ with amino acids, peptides, or dicarboxylic acids was investigated at 25°C and 0.1 M ionic strength. Amino acids and dicarboxylic acids form 1 : 1 complexes. Peptides form both 1 : 1 complexes and the corresponding deprotonated amide species. The stability of the complexes formed was determined and the binding centres of the ligands were assigned. Effect of solvent on the stability constant of Pd(MME)-CBDCA complex, taken as a representative example, shows that the complex is more favoured in a medium of low dielectric constant. The concentration distribution diagrams of the complexes were evaluated
Comparative Study of RP-HPLC and UV Spectrophotometric Techniques for the Simultaneous Determination of Amoxicillin and Cloxacillin in Capsules
Reversed-phase HPLC and UV spectrophotometric techniques using water as solvent have been developed and validated for the simultaneous determination of amoxicillin and cloxacillin in capsules. For both techniques, the linearity range of 60.073x2013;140.0 µg/mL was studied. The spectrophotometric data show that non-derivative techniques, such as absorbance ratio and compensation, and ratio spectra first-order derivative could be successfully used for the co-assay of amoxicillin and cloxacillin. Based on the statistical comparison of spectrophotometric and chromatographic data, the interchangeability between HPLC and UV spectrophotometric techniques has been suggested for the routine analysis
Small intestinal obstruction due to phytobezoar: a case report
<p>Abstract</p> <p>Introduction</p> <p>Patients with mechanical small-bowel obstructions usually present with abdominal pain, vomiting, absolute constipation and varying degrees of abdominal distention. Causes can be classified as benign or malignant, or as extra- or intraluminal. A bezoar occurs most commonly in patients with impaired gastrointestinal motility. In edentulous older patients with abnormal food habits, it can also be an intestinal concretion that fails to pass along the alimentary canal.</p> <p>Small bowel phytobezoars are rare and almost always obstructive. In a normal stomach, vegetable fibres that cannot pass through the pylorus undergo hydrolysis within the stomach, which softens them enough to go through the small bowel.</p> <p>We present an unusual case of small intestinal obstruction caused by a phytobezoar in a patient who had neither a history of gastric surgery nor of intestinal pathology.</p> <p>Case presentation</p> <p>A 70-year-old Iraqi Kurdish man was hospitalized due to abdominal pain, vomiting and dehydration. Investigations concluded small intestinal obstruction. Subsequent laparotomy revealed that the cause of the obstruction was an eggplant phytobezoar.</p> <p>Conclusion</p> <p>Many types of bezoar can be removed endoscopically, but some will require operative intervention. Subsequently, prevention of any recurrence should be emphasized.</p
Variation between some apricot varieties in regard to flowering phenology in Boldogkôváralja, Hungary
The aim of this study was the estimation of blossoming of 14 apricot cultivars in Boldogkôváralja in 2009, 2010 and 2011 seasons.And this will help growers to select appropriate varieties to their weather conditions. For this target the blooming period of 19 apricot varietiesof different origin was observed in three subsequent years. There was no large difference in the beginning of blooming in the different years,and the greatest variation between the start date of flowering was about 1 to 3 days as the place of experiment site near to northern border andalso, length of flowering period of apricot trees is also inversely related to date when blooming started. The little differences in flowering datesand flowering periods due to the high temperature through the three seasons of study

Storability of some apricot varieties as affected by storage period
The aim of this study was the estimation of storability of 10 apricot varieties in regard to percentage fruit weight loss, firmness,acidity and T.S.S in fruit during storage periods from one week to 4 weeks. All the variety gave the same trend as all of them loss weight,firmness decreased, acidity and T.S.S decreased but the differences were not the same in all varieties. in case of some varieties the percentageof fruit weight loss reached to about 9 % after 28 days also the differences between varieties in two seasons refer that this character isdetermined by genetic factors beside effect of environmental and agriculture factors

Co-development and evaluation of the Musculoskeletal Telehealth Toolkit for physiotherapists
Introduction In-person physiotherapy services are not readily available to all individuals with musculoskeletal conditions, especially those in rural regions or with time-intensive responsibilities. The COVID-19 pandemic highlighted that telehealth may facilitate access to, and continuity of care, yet many physiotherapists lack telehealth confidence and training. This project co-developed and evaluated a web-based professional development toolkit supporting physiotherapists to provide telehealth services for musculoskeletal conditions.
Methods A mixed-methods exploratory sequential design applied modified experience-based co-design methods (physiotherapists [n = 13], clinic administrators [n = 2], and people with musculoskeletal conditions [n = 7]) to develop an evidence-informed toolkit. Semi-structured workshops were conducted, recorded, transcribed, and thematically analysed, refining the toolkit prototype. Subsequently, the toolkit was promoted via webinars and social media. The usability of the toolkit was examined with pre-post surveys examining changes in confidence, knowledge, and perceived telehealth competence (19 statements modelled from the theoretical domains framework) between toolkit users (>30 min) and non-users (0 min) using chi-squared tests for independence. Website analytics were summarised.
Results Twenty-two participants engaged in co-design workshops. Feedback led to the inclusion of more patient-facing resources, increased assessment-related visual content, streamlined toolkit organisation, and simplified, downloadable infographics. Three hundred and twenty-nine physiotherapists from 21 countries completed the baseline survey, with 172 (52%) completing the 3-month survey. Toolkit users had greater improvement in knowledge, confidence, and competence than non-users in 42% of statements. Seventy-two percentage of toolkit users said it changed their practice, and 95% would recommend the toolkit to colleagues. During the evaluation period, the toolkit received 5486 total views.
Discussion The co-designed web-based Musculoskeletal Telehealth Toolkit is a professional development resource that may increase physiotherapist's confidence, knowledge, and competence in telehealth
