This study aimed to know the physiological changes of some blood indicators (creatinine - urea - red and white blood cells) for patients with chronic renal failure. To achieve the objectives, the study was conducted on 50 people (40 people with chronic renal failure) and (10 healthy people) for the age groups (15 - 58) years, males and females, the study was conducted from the end of April to the end of June 2024 at the Hemodialysis Center - Al-Jumhuriya Teaching Hospital, Aden Governorate.                                                                     

The study samples were divided into five groups, each group containing 10 people, according to gender (males, females), where some blood indicators were estimated, and the levels of urea, creatinine, red blood cells and white blood cells were measured in the serum of patients and healthy people.        

The results showed that there were highly significant differences in the average concentration of creatinine and urea levels for the four groups in patients with chronic renal failure compared to the healthy group (normal) and a decrease in the average red and white blood cell count in patients with chronic renal failure compared to the healthy group.                                           

We conclude from the study that the increase and decrease in Blood indices such as creatinine, urea, red blood cells and white blood cells negatively affect people with chronic kidney disease.

An experiment was conducted on the research farm of Faculty of Agriculture and Food Sciences, Ibb University, Yemen, in 2014-2016 to identify the effect of four levels of potassium fertilizer (48% of potassium sulphate) on Arabica apple coffee, namely T1 (0), T2 (50), T3 (60), and T4 (70) g/tree. Then, 2 kg/tree of an organic fertilizer, and 50g/tree of phosphorous fertilizer were added. The experiment was carried out by using a complete random pieces design (RCBD) with four replicates where each replicate contained 4 trees. Next, the field received a drip irrigation along periods separated by 7 to 12 days.

The findings of the study showed that in June of the first year 2014-2015, there were statistically significant differences at the level (P ≤ 0.05) in lengths between the third treatment and other treatments. In May, there were statistically significant differences in branches between the second treatment and other treatments, showing no significant differences between lengths and branches in the other months. In the second year 2015-2016, there were no statistically significant differences in lengths and branches in July, September, October and February, while there were in branches in August and December between the second and first treatments. In November, January, March, April and May, there were statistically significant differences between the three treatments, and the first treatment (control). In June, there were statistically significant differences between the second and fourth treatments, and the first one. Concerning productivity of trees in the first year, there were statistically significant differences at the level (P ≤ 0.05) between T2, T3 and T4, and the control one. Finally, in the second year, there were statistically significant differences between both T3 and T4, and both second and control treatments, showing that the T4 scored the top rank in productivity (1189 g/tree).

Vernonia amygdalina Delile, commonly known as bitter leaf, is a widely recognized medicinal plant in Africa but remains largely underexplored in Yemen. This study aimed to investigate the phytochemical profile, antioxidant capacity, and antibacterial activity of the methanolic leaf extract of V. amygdalina collected from Socotra Island. Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, tannins, saponins, terpenoids, cardiac glycosides, phenols, and steroids. Quantitative estimation demonstrated a high total flavonoid content (238.4 ± 4.2 mg QE/g) and substantial total phenolic content (122.6 ± 3.1 mg GAE/g). Antioxidant evaluation using the DPPH radical scavenging assay showed strong free radical inhibition, with 84.7% activity at 400 µg/mL and an IC₅₀ value of 96.4 µg/mL, while the ferric reducing antioxidant power assay indicated strong electron-donating potential (OD₇₀₀ = 0.732). Antibacterial testing against clinical isolates showed concentration-dependent inhibition. MIC values were 50 mg/mL for Staphylococcus aureus and S. epidermidis, while Gram-negative bacteria (E. coli, K. pneumoniae, and P. aeruginosa) exhibited higher MIC values (100 mg/mL) with MBCs exceeding 200 mg/mL. These findings support the traditional use of V. amygdalina and highlight the Socotra accession as a promising, locally accessible source of bioactive compounds with antioxidant and antibacterial potential. Further work should isolate active constituents and assess in vivo efficacy and safety.

One easy way to remove synthetic colors from aqueous solutions is to adsorb them on inexpensive solid sorbents. Utilizing activated carbon from polymer waste has been the focus of recent sorption process initiatives, therefore it offers a more appealing and affordable option than commercial activated carbon, which is often more costly. This study seeks to investigate the equilibrium and sorption kinetics of two artificial cationic and Ionic dyes from aqueous media which are respectively crystal violet and methylene orange utilizing Polyethylene Terephthalate PET waste to produce activated carbon. Based on FTIR analysis, the adsorbent possesses an OH functional group in C6H8O7 modified carbon-2 and KOH modified carbon-2 of a ratio preparation of 1:2, C-H , C=O and C-O. SEM analysis indicated the presence of pores of different sizes and shapes in micrometer diameter.  Additionally, XRD images detected  C6H8O7 modified carbon-2/C-500 had small sharp peaks revealed in 2θ = 29°, 2θ = 41°and 2θ = 51°. The results suggest that these peaks reflect the condensed aromatic carbonized planes. Batch adsorption studies were performed to investigate the a effect of initial PH, contact time, initial CV and MO concentration, adsorbent dosage and temperature on adsorption. The Langmuir and Freundlich isotherm models provided the explanation for experimental data with the highest correlation coefficient with CV dye, whereas the Freundlich isotherm model is suitable to describe the adsorption reaction of the MO dye. Sorption thermodynamic data show that the adsorption process is spontaneous in all samples except (C6H8O7modified carbon-1) was  nonspontaneous. Moreover endothermic in all the samples  except (C6H8O7modified carbon-2) was exothermic sample and the clearing PET waste obtained after surface modification by C6H8O7  treatment showed a higher adsorption capacity from  KOH.

This paper investigates the relationship between Cartan’s second curvature tensor and Weyl’s projective curvature tensor in the context of Riemannian spaces. The study focuses on deriving a formula that connects these two curvature tensors and exploring the implications of their interactions. Key results of this work include the establishment of a set of equations that describe the covariance and transvectivity of these tensors under various conditions, leading to the formulation of several theorems. The findings provide new insights into generalized birecurrent Finsler spaces and their geometric properties, contributing to the understanding of curvature tensors in higher-dimensional spaces.

In this paper, we introduce generalized q-Humbert function, some properties of this function, q-difference equations and recurrence relations are derived.

Background: Yemeni patients, faced with limited healthcare infrastructure at home, increasingly seek treatment abroad, particularly in India.

Objective: To evaluate the satisfaction rates of Yemeni patients with the services offered by the Yemeni Medical Attaché in Mumbai.

Materials and Methods: The type of the study is a descriptive research, which targeted Yemeni patients who engaged with the Yemeni Medical Attaché services in Mumbai between January 2022 and December 2024. A simple random sampling technique was employed. A total of 300 patients participated in this study. The data collection tool was a structured questionnaire.

Data were analyzed using SPSS version 22. Descriptive statistics (means, percentages) summarized patient satisfaction levels. Inferential statistics (Chi-square test, ANOVA) examined associations between demographic factors and satisfaction levels. P-value < 0.05 was considered as statistically significant.

Results: During the three years, study period, 300 patients randomly selected for this study. There were (61.3%) males and (38.7%) females. The mean age of the patients was (42.12 ± 13.8) years, range (18– 70) years. The age group 18 – 39 years represented the higher number of study patients (46.0%). Patients with cardiac conditions represented the higher number of patients (65%). Patients’ satisfaction related to administrative assistance was predominant and found (80.5%) patients. The satisfaction related to communication and follow-up found in (70.4%) patients. Patients’ satisfaction was found with highest percentage in female patients with (76.7%) and by male patients were in (72.8%) (p > 0.05). The satisfaction rate by the age group 18 – 39 years old was more frequently observed with (36.3%) patients, followed by the age group 40 – 59 years old with (22.0%). The difference between values is statistically highly significant (p = 0.000).

 Conclusion: While the Yemeni Medical Attaché in Mumbai demonstrates a generally positive performance, targeted efforts to improve transparency and emergency handling are recommended. Periodic assessments are essential to sustain and enhance patient satisfaction.
