Abstract	Current research is moving towards iron and ammonia elimination from groundwater. Here, we are using a poly acrylic-poly acrylamide hydrogel that is grafted with 3-chloroaniline. This copolymer was synthesized by addition polymerization technique. The effects of agitation time, dosage and adsorbent temperature on the removal process sensitivity were investigated. The copolymer was described experientially and theoretically. Isothermal kinetic adsorption models are discussed. This hydrogel could be regenerated efficiently (98.3% removal of iron and 100% removal of ammonia). The density functional theory (DFT) method, using B3LYP/6-311G(d,p), and the LANL2DZ level of the theory were managed to investigate the stationary states of the grafted copolymer and the complexation energy of the hydrogel with the studied cations. DFT has been used to investigate the Natural Bond Orbital (NBO) properties to locate the most negative centers on the hydrogel. The calculated complexation energy showed hydrogel selectivity with regard to the studied cations.

Abstract	Metabolic syndrome (MetS) is a group of cardiovascular risk factors which has higher prevalence in the elderly population. Being an aged obese woman with raised arterial blood pressure and blood glucose level might increase the risk of having cardiovascular morbidity or mortality during an attack of myocardial infarction. The present study was designed to evaluate the cardioprotective efficacy of a low intensity swim-exercise program on ischemic reperfusion injury in isolated perfused hearts from aged female rats with MetS. Wistar rats were allocated into three groups: controls, MetS-sedentary, and MetS-exercised. Body weight (BW) and waist circumference were measured with calculation of body mass index (BMI). Blood pressure, fasting blood glucose (FBG) and lipid profile were determined. Cardiac activities of isolated hearts were studied on Langendorff preparation under basal conditions and following ischemia/reperfusion (I/R), and the level of cardiac tissue nitrite was also assessed. MetS-exercised rats showed restoration of control values for BW, BMI, waist circumference, visceral fat, FBG, plasma lipid profile and left ventricular nitrite content. Meanwhile, arterial blood pressure was significantly lower than both controls and MetS-sedentary rats. These findings suggest that a short-term, low-intensity exercise program can improve cardiac tolerance to I/R injury possibly by ameliorating the high-risk cardiovascular components of the MetS.

Abstract	Background: Swimming pools are places for practicing sports, recreation, relaxation, and socialization. However, swimming pools can expose swimmers to physicochemical and microbiological risks. Accordingly, we studied the environmental health aspects and microbial infections for such recreational water aiming to disclose the possible risks they pose on swimmers. Methods: 26 pools in Alexandria, Egypt were checked for water quality; 13 pools were checked in winter then summer, and other 13 pools were checked in summer only. Water was collected from both the top and the bottom of each pool; a total of 78 samples were collected in sterile containers. Each sample was divided into three parts; the first part was used for assessing the bacteriological quality of water. They were tested for total colony count (TCC), total coliform (TC), fecal coliform, and E. coli. The second part was used for chemical analysis. The third part was checked for parasitological study. Results: Obtained data showed that only 7.7%, 78.2%, and 100% of the examined water samples have been found to fulfill the Egyptian standards for TCC, TC, and E. coli, respectively. Moreover, parasitic infection (PI) was noticed in 73.1% of the collected water samples; mainly Cyclospra and Isospora (37.2% each), followed by Cryptosporidium spp., Giradia lamblia, Microsporidia spp., and Blastocystis spp. (34.6%, 21.8%, 15.4%, and 14.1%, respectively). Acanthameba spp. was detected but at a lower rate (5.1%). The frequency of cleaning the swimming pools, flow rate, Cl Conclusion: The tested water samples don't meet Egyptian bacteriological criteria. High parasitic contamination despite high residual chlorine level mainly intestinal coccidia, G. lamblia, microsporidia, and Blastocystis spp. Thus, monitoring pool's water quality and improving the disinfection system are mandatory. Consequently, Health education regarding hygienic behaviors before and during swimming should be included in governmental programs.

Abstract	Objective: Nonsteroidal anti-inflammatory drugs (NSAIDs) are a group of drugs widely used around the world for their analgesic, antipyretic and anti-inflammatory effect, but still have many limitations due to their side effects. So, these lead to the development of a new approach to search for a new product from natural plants that have similar therapeutic effects without common side effects like gastrointestinal ulcers. Methods: The anti-inflammatory effect of β-amyrin palmitate (1) as triterpene and 1,7-bis (4- hydroxyphenyl) hept-4-en-3-one (2) as diarylheptanoid, isolated from Pellacalyx axillaris was studied by molecular docking to find the probability of binding position and binding strength of new compounds with particular Prostaglandin G/H synthase 2 (PDB ID: 1CX2). In vivo acute anti-inflammatory activity of the isolated compounds (1 and 2) was evaluated in rats using the egg-white induced edema model of inflammation in a dose correspondent to 3 mg/Kg of Diclofenac Sodium. Results: The tested isolated compounds showed a high activity to inhibit the swelling in paw edema and their anti-inflammatory effect began shortly after the injection of the egg white and continued to the end of the experiment in comparison to the reference and control. Conclusion: The isolated compounds show a rapid onset of action and a very potent effect, this may be related to their suitable acidity and may have perfect hydrophilic -lipophilic balance. This is the first study of anti-inflammatory effect using Paw edema model and molecular docking.

Abstract	Introduction: Hyponatraemia is the most common electrolyte disorder in inpatients resulting mainly from an imbalance in water homeostasis. Intravascular fluid status assessment is pivotal but is often challenging given multimorbidity, polypharmacy and diuretics use. We evaluated the utility of point-of-care ultrasound (POCUS) as an adjunct tool to standard practice for fluid assessment in severe hyponatraemia patients. Methods: Patients presenting with severe hyponatremia (Serum Sodium [Na] < 120 mmol/L; Normal range: 135-145 mol/L), managed by standard care were included. Hyponatraemia biochemistry work-up and POCUS examination were undertaken. Both clinician and POCUS independently assigned one of the three fluid status groups of hypovolaemia, hypervolaemia or euvolaemia. The final diagnosis of three fluid status groups at admission was made at the time of discharge by retrospective case review. Clinician's (standard of care) and POCUS fluid assessments were compared to that of the final diagnosis at the time of discharge. Results: n = 19 patients were included. Median Na on admission was 113 mmol/L (109-116), improved to 129 ± 3 mmol/L on discharge. POCUS showed the higher degree of agreement with the final diagnosis (84%; n = 16/19), followed by the clinician (63%; n = 12/19). A trend towards higher accuracy of POCUS compared to clinician assessment of fluid status was noted (84% vs. 63%, p = 0.1611). Biochemistry was unreliable in 58% (n = 11/19) likely due to renal failure, polypharmacy or diuretic use. Inappropriate emergency fluid management was undertaken in 37% (n = 7/19) of cases based on initial clinician assessment. Thirst symptom correlated to hypovolaemia in 80% (4/5) cases. Conclusion: As subjective clinical and biochemistry assessments of fluid status are often unreliable due to co-morbidities and concurrent use of medications, POCUS can be a rapid objective diagnostic tool to assess fluid status in patients with severe hyponatraemia, to guide accurate emergency fluid management.

Abstract	Groundwater, is an alternative resource, is used as a supplement for irrigation as well as drinking purposes in Pakistan. This paper aims to determine the quantum and quality of groundwater in Matiari district of Sindh, Pakistan, through Electrical Resistivity Survey (ERS). The ERS was conducted at 52 location points using the ABEM Terrameter SAS 4000. The quantity of good quality groundwater has also been evaluated with ArcGIS interpolation techniques, i.e., the maximum percentage of fresh groundwater is 34% the marginal fresh groundwater 43% at the depth of with few patches of saline groundwater aquifers. Moreover, at 50-m depth, the percentage of fresh groundwater reduces to 21% and the marginal has increased to 48%. However, groundwater below the depth from 50 to 100 m was found only 8% fresh groundwater, 29% marginal, 49% salt water, and 14% high salt water. Analysis of groundwater samples for quality showed a good agreement with the quality obtained from VES results. In addition, a socio-economic survey of 55 tube well owners were conducted through interviews related to groundwater suitability and usage. According to the survey, about 62% of respondents are using good quality groundwater; however, 36% consuming the marginal and the remaining 2% are utilizing the hazardous quality of groundwater. The consumer satisfaction survey showed most farmers (89%) were satisfied with the groundwater usage, while 11% were unsatisfied due to poor-quality groundwater. The crop productivity could be enhanced through awareness and conjunctive use of marginal quality groundwater with the canal water.

Abstract	Public health is a major concern globally, owing to the presence of industrial dyes in the effluent. Nanoparticles with green synthesis are an enthralling research field with various applications. This study deals with investigating the photocatalytic potential of Fe-oxide nanoparticles (FeO-NPs) for the degradation of methylene blue dye and their potential biomedical investigations. Biosynthesis using Anthemis tomentosa flower extract showed to be an effective method for the synthesis of FeO-NPs. The freshly prepared FeO-NPs were characterized through UV/Vis spectroscopy showing clear peak at 318 nm. The prepared FeO-NPs were of smaller size and spherical shape having large surface area and porosity with no aggregations. The FeO-NPs were characterized using XRD, FTIR, HRTEM, SEM and EDX. The HRTEM results showed that the particle size of FeO-NPs was 60-90 nm. The antimicrobial properties of FeO-NPs were investigated against two bacterial Staphylococcus aureus 13 (±0.8) and Klebsiella pneumoniae 6(±0.6) and three fungal species Aspergillus Niger, Aspergillus flavus, and Aspergillus fumigatus exhibiting a maximum reduction of 57% 47% and 50%, respectively. Moreover, FeO-NPs exhibited high antioxidant properties evaluated against ascorbic acid. Overall, this study showed high photocatalytic, antimicrobial, and antioxidant properties of FeO-NPs owing to their small size and large surface area. However, the ecotoxicity study of methylene blue degradation products showed potential toxicity to aquatic organisms.

Abstract	BACKGROUND & OBJECTIVE: Palatine tonsils are lymphoid organs in the oropharynx part of the waldeyer's ring and serve as host defence organs with maximum immunological activity from 3-10 years. Tonsillectomy is associated with considerable postoperative pain and requires significant consumption of analgesia. This study aimed to determine effect of topically suffused 0.5% bupivacaine on postoperative tonsillectomy pain. RESULTS One hundred & twenty (120) patients with 61 males and 60-patients in each group with age range of 5-15 years (Group-A=8.63±2.63 and Group-B=8.32±6.60 in). Mean BMI of Group-A and group-B was 15.18±1.60 and 14.96±1.34 respectively (p=0.417). Mean pain score in group-A and group-B was 2.63±0.938 and 6.07±0.800 respectively (p<0.001). CONCLUSION: nsillectomies performed using bupivacaine-soaked packs postoperatively are associated with lower postoperative pain compared with those packed with normal saline.
