Introduction: Diabetes mellitus has become a serious warning to mankind health all over the world. The
management goal of diabetes is to keep blood glucose levels as close as possible to healthy individuals.
Medications used to treat diabetes are usually associated with complications and may cause different side
effects. Many traditional anti-diabetic plants have become popular in the management of diabetes mellitus.
Flaxseed has been used as traditional medicine for centuries. Objective: This study aimed to evaluate the
hepatoprotective effects of flaxseed extract in streptozotocin (STZ)-induced diabetic rats. Methods:
Diabetes mellitus was induced in Sprague-Dawley rats using a single injection of streptozotocin (60 mg/kg
i.p.). The rats were divided into five groups of 8 rats each. Group NC, normal control rats; Group NF, normal
rats treated with flaxseed extract (400 mg/kg); Group DC, diabetic control rats; Group DG, diabetic rats
treated with glibenclamide (0.6 mg/kg); Group DF, diabetic rats treated with flaxseed extract (400 mg/kg);
for 4 weeks. Results: There were significant increase in relative liver weight, blood glucose levels in DC
group comparing to NC group (p<0.05). The disturbance of these parameters was ameliorated in DF and DG
groups. Histological observation revealed congestion of central veins, degeneration of hepatocytes, and
reduced glycogen granules in DC group. These pathological changes were ameliorated in the flaxseed
extract and glibenclamide treated rats. Conclusion: Flaxseed extract may represent a candidate alternative
treatment to control diabetes mellitus and its related hepatopathy.

Purpose:
This study aims to explore the feasibility and implications of Ramadan fasting for patients who have undergone laparoscopic sleeve gastrectomy (LSG), assessing impacts on hydration, nutrient intake, weight management, and gastrointestinal symptoms.
Methods:
A prospective online survey was conducted among 218 LSG patients and 83 control individuals with obesity who had not undergone surgery. Participants were surveyed before and after Ramadan, providing data on fasting practices, hunger and satiety levels, fluid and nutrient intake, and the occurrence of gastrointestinal symptoms. Statistical analysis was used to compare outcomes between fasting and non-fasting periods and between LSG patients and control participants.
Results:
A total of 70.2% of LSG patients completed the entire month of Ramadan fasting, with a significant correlation found between the duration post-surgery and the ability to fast. Fasting LSG patients reported decreased hunger, increased satiety, and significant reductions in fluid and nutrient intake during Ramadan. Weight loss was reported in 90.8% of fasting patients, with an average total weight loss of 7.2%. Gastrointestinal symptoms were mild and manageable.
Conclusion
The majority of LSG patients can successfully fast during Ramadan with appropriate precautions, including adequate fluid and protein intake. The study highlights the need for patient education and tailored nutritional guidance to ensure safe and effective fasting post-LSG. In order to fast for the entire month, patients may be advised to consider postponing surgery for a few months after Ramadan, avoid overeating during non-fasting hours, and ensure sufficient fluid consumption and protein intake during fasting.

Objectives: In Northern Africa, the region Egypt belongs to, about 10.7% of women are estimated to
harbour cervical human papillomavirus (HPV) infection and 78.4% of invasive cancers are attributed to
HPVs 16 or 18. We aimed at comparing HPV detection by ISH-PCR tissue with other conventional
available cheaper techniques, finding which of them can be relied upon in a developing country like
Egypt for HPV detection. Methods: Sixty patients were included. For them colposcopy, PAP smear,
histopathology and detection of HPV using ISH PCR tissue and PCR swab were achieved. Results:
PCR-ISH tissue was positive in 53.33%, 46.6% were negative. Pap smear was negative in 26 cases
(43.33%) and 43 cases (56.67%) were positive. LSIL with perinuclear halo represented nearly half of
the positive cases (16/34; 47.05%), 10 cases were diagnosed as HSIL, 4 cases as ASCUS and 4 as AGC.
Histopathology was negative in 12 (20%) cases and 48 (80%) cases were positive. CIN I and CIN I+
koliocytosis represented half of the cases (30/60) and more than half of positive cases (30/48; 62.5%).
Comparing the results of pap smear, histopathology, colposcopy and PCR swab with ISH PCR tissue,
highly significant results were seen with sensitivity of 87.5%, 100%, 62.5% and 56.2% respectively but
the specificity were 78.6%, 42.9%, 28.6% and 100% respectively. Conclusion: Conventional cytology
and histopathology were sensitive tests for detection of HPV. This may help for early detection of
cancer cervix in a developing country like Egypt. PCR swab showed the highest specificity and the
lowest sensitivity.

BACKGROUND AND OBJECTIVES: The utilization of the stem cells is widely used in the last few years in different fields of medicine, either by external transplantation or endogenous mobilization, most of these studies still experimental on animals; few were tried on human as in the spinal cord injury or myocardial infarction. As regard its use in the inner ear, stem cell transplantation was examined in many previous studies, while the mobilization idea is a new method to be experimented in inner ear hair cell regeneration. The present work assessed the possibility of mobilizing endogenous bone marrow derived stem cells (SCs) in rats using granulocyte colony stimulating factor (G-CSF) to induce regeneration and repair to experimentally damaged inner ear hair cells by Amikacin injection. METHODS: The study included thirty adult Sprague Dawley male rats. Experimental induction of inner ear damage was done by repeated intratympanic injection of amikacin sulfate. Mobilization of bone marrow SCs was provoked by subcutaneous injection of GCSF. Cochlear integrity, induction of hearing loss and functional recovery of sensory hearing loss were assessed using Distortion Product Otoacoustic Emission (DPOAEs). The morphological alteration and recovery of the organ of Corti was assessed histologically using the light and scanning electron microscopes. RESULTS: After six month duration, there was improvement in 50% of the sensorineural DPOAE results. Functional recovery coincided with the repair of structural components of organ of Corti. CONCLUSIONS: SCs mobilization by G-CSF is a promising alternative method for replacement therapy in sensorineural hearing loss.

Background:
Atrial tachycardia poses challenges in patient management due to the associated risks of stroke and systemic embolism. While anticoagulation is recommended in atrial fibrillation (AF), its role in atrial tachycardia remains less defined. This prospective study aimed to evaluate the efficacy and safety of apixaban, a direct oral anticoagulant, in individuals diagnosed with left-sided atrial tachycardias.
Methods:
Patients diagnosed with left-sided atrial tachycardia (n = 439) were observed over 3 years. Baseline characteristics, medication regimens, and clinical outcomes were assessed. Apixaban-treated individuals (n = 213) received standard or reduced dosages, while the control group (n = 226) received standard care. Primary outcomes included stroke, systemic embolism, bleeding, and mortality rates.
Results:
Baseline characteristics were comparable between groups. The apixaban cohort showed a lower incidence of stroke (7.0% vs. 9.3%, p = 0.027) and decreased all-cause mortality (11.7% vs. 12.8%, p = 0.012) compared to controls.No significant differences were found in major bleeding or systemic embolization between groups.
Conclusion
Apixaban demonstrated a potential benefit in reducing stroke and mortality rates in patients with leftsided atrial tachycardia. While requiring further validation, these findings suggest a potential role for apixaban in anticoagulation strategies for atrial tachycardia management.

Lactate dehydrogenase was purified 21-fold from liver of Varanus bengalensis using colchicine-sepharose column chromatography. The crude enzyme showed two isoenzymes (LDH-5 and LDH-4) by agarose gel electrophoresis (AGE). The purified enzyme showed a single band after SDS-PAGE corresponding to molecular mass of 35 kDa. The molecular mass of native enzyme was about 140 kDa. The optimum pH for the forward reaction was 7.5 while that for the reverse reaction was pH 9.5. The K-m values for pyruvate, NADH, lactate and NAD(+) were 0.17 +/- 0.037, 0.02 +/- 0.004, 12.4 +/- 3.05 and 0.38 +/- 0.032 mM, respectively. Pre-heating of enzyme showed that its t(50) was 40-50 degrees C. Oxalate and n-hexanediol were inhibitors for both forward and reverse reactions. Among divalent ions, Cu++ was shown to be more effective inhibitor for the forward reaction.

BACKGROUND AND OBJECTIVES: The present study investigated whether MSCs derived microvesicles (MVs) or (Exosomes) can exert therapeutic effects on an experimental model of cutaneous injury and explored the underlying involving mechanisms. METHODS AND RESULTS: Three bilateral full thickness circular wounds were created on the back of two groups of dogs using 2-cm dermal punch. The wounds were at least 2.5 cm apart. Saline was subcutaneously injected in 4 places around each wound area in group-I (control), whereas an equal volume of exosomal solution of MSCs derived MVs was similarly injected in group-II. The findings demonstrated that MSCs derived MVs had significantly promoted cutaneous wound healing, collagen synthesis, and vascularization at wound sites. The application of the exosomal solution had not only promoted the generation of newly formed vessels, but also have accelerated their development and maturation leading to a faster healing process. CONCLUSIONS: MSC-Exosomes appeared to be a superior candidate for treating cutaneous wounds than their originator cells, and may represent a promising opportunity to develop a novel cell-free therapy approach that might overcome the obstacles and risks associated with the use of native or engineered stem cells transplantation therapy.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common reproductive disorder. Obesity, which is linked with lower adiponectin levels, increases a woman's risk of developing PCOS; however, the association between adiponectin and PCOS is controversial. Adiponectin levels could be affected by single nucleotide polymorphisms (SNPs) in the ADIPOQ gene. This study aimed to test the relationship between serum adiponectin and PCOS in Jordan and the association between the rs2241766, rs1501299, and rs266729 SNPs in the ADIPOQ gene and PCOS. METHODS: One hundred and fifty-four women with PCOS and 149 age- and body mass index–matched normally menstruating controls were recruited. Serum adiponectin levels were measured using enzyme-linked immunosorbent assay. Genotyping was performed using polymerase chain reaction–restriction fragment length polymorphism analysis. RESULTS: Serum adiponectin levels were significantly lower (P=0.0064) in PCOS women and rs1501299 (+276 G/T) genotype distributions were significantly different (P=0.01) between them and normally menstruating women. Multivariate analysis revealed that adiponectin levels remained significantly lower in PCOS women (P=0.001; odds ratio [OR], 0.9; 95% confidence interval [CI], 0.84–0.96). The GT genotype of rs1501299 increased the risk of PCOS (P < 0.001; OR, 5.46; 95% CI, 2.42–12.33) and increased the risk of PCOS by three-fold (P < 0.001; OR, 3.00; 95% CI, 1.36–6.60) relative to the TT genotype. The GG genotype increased the risk of PCOS as well (P < 0.001; OR, 3:00; 95% CI, 1.36–6.60). CONCLUSION: PCOS is associated with lower serum adiponectin levels independent of age and body mass index. The T allele of the rs1501299 (+276 G/T) SNP of the ADIPOQ gene protects against PCOS.

Clinical and Experimental Vaccine Research 2021;10(2):171-182
Purpose:
Vaccination is a cost-efficient intervention to slow the spread of the coronavirus disease 2019 (COVID-19) pandemic. This study aims to assess the population's willingness to take the COVID-19 vaccine in Jordan and investigate potential determinants of their acceptance
Materials and Methods:
This study used an online survey distributed in November 2020, before introducing the vaccine, with items investigating socio-demographic characteristics, seasonal flu vaccination history, COVID-19 vaccine acceptance once available, and factors affecting their decision-making. Also, “COVID-19 risk perception” and beliefs toward COVID-19 vaccine benefits and barriers were assessed.
Results:
A total of 2,208 participants completed the survey with a participation rate of 13.1%. The mean±standard deviation age was 33.2±13.5, and 55.7% were females. Study participants were almost equally distributed between willingness, unwillingness, and indecision to take the COVID-19 vaccine (30.4%, 36.4%, and 31.5%, respectively). Younger adults, males, and those who were not married, do not have children, have a bachelor or higher education, employees or being students, healthcare workers, and those who reported receiving flu vaccine had higher rates of COVID-19 vaccine acceptance compared to their counterparts (p<0.001 for each category). COVID-19 risk perception, and perceived vaccine benefits, and barriers were significant predictors of intention. Among those undecided or unwilling to take the COVID-19 vaccine, its safety and side effects were the most common concerns.
Conclusion
The low rate of COVID-19 vaccine acceptance in a developing country is alarming, and a significant proportion are indecisive. Interventions to elevate vaccine acceptance by addressing its safety and efficacy and targeting vulnerable groups are recommended.
