This study in Aden, Yemen, collected 67 samples from patients attending hospitals and laboratories. Samples were taken from different body areas, covering various age groups and genders. Fungal infections, particularly Candida species, are a significant cause of death worldwide. The emergence of azole-resistant Candida has raised concerns and highlighted the need for better antifungal agents.
In the study, 68.66% of the collected samples contained pathogenic Candida fungi. Some samples also showed bacterial growth or both bacteria and fungi. Suspected Candida growth on corn meal agar exhibited chlamydospore formation and germ tubes on human serum. Carbohydrate fermentation tests were positive for Glucose, Maltose, Galactose, and Xylose, while Sucrose and Lactose were negative. All Candida isolates (100%) were accurately identified to the species level using CHROM agar Candida. Candida's pathogenicity was linked to various virulence factors, including hydrolytic enzyme secretion. Nystatin was the most effective antifungal agent (100% sensitivity), while Fluconazole (73.92%) and Amphotericin B (52.17%) showed varying levels of sensitivity. However, Voriconazole, ketoconazole, and Miconazole displayed high resistance rates (89.13%, 84.78%, and 80.44%, respectively) against the isolated Candida.
This study concluded that Candida spp., particularly Candida albicans, were frequently found in the samples from patients, with vaginal swaps being a common site of infection. The identification of Candida isolates to the species level using CHROM agar Candida was accurate. Nystatin, Fluconazole, and Amphotericin B were the most effective antifungal agents against Candida spp.

Finsler geometry has many uses in relative physics and many of mathematicians contributed in this study and improved it. Takano [26] has studied the decomposition of curvature tensor in a recurrent space. Sinha and Singh [25] have studied and defined the decomposition of recurrent curvature tensor field in a Finsler space. Negi and Rawat [11] and [12] have studied decomposition of recurrent curvature tensor fields in K¨aehlerian space. Rawat and Silswal [19] studied and defined the decomposition of recurrent curvature tensor fields in a Tachibana space. Rawat and Singh [21] studied the decomposition of curvature tensor field in K¨aehlerian recurrent space of first order. Further, Rawat and others [20],[22] and [23] studied the decomposition of curvature tensor field in Einstein- K¨aehlerian recurrent space of first order. Al-Qashbari [1], [2], [3] and [4] and Qasem and others [14], [15], [16], [17] and [18] studied the recurrent for different curvature tensors .In the present paper, we have studied the decomposition of curvature tensor fields \(R_jkh^i\) in recurrent space of First order and second order, and several theorems have been established and proved.

For a polynomial P(z) of degree n , having all zeros in |z|≤1, Malik [11] proved that for each q>0,
\(n [∫_0^{2π} |P(e^{iθ})|^q dθ] ^{1⁄q} ≤[∫_0^{2π} | 1 + e^{iθ} |^q dθ]^{1⁄q} \underset{|z|=1}{max} |P^ʹ (z)|\). In this paper we generalize the above inequality to polar derivative and generalized polar derivative, which as special cases include several known results in this area.

The acute abdomen accounts for 5% to 25% of all emergency department visits of 5 to 10 million patient encounters in the United States annually. The main objective of this study was to assess the surgical treatment outcomes for clinicopathological patterns of acute abdomen. This prospective descriptive study was conducted on 84 consecutive patients who underwent surgery in Al-Gamhouria Hospital within a period between January and December 2016. 
The incidence of the acute abdomen was 12.03% (84) of the total population of the surgical emergency cases in the study period. The male to female ratio of 1.6:1 and the mean age was 29.13 ± 17.10 years. Acute appendicitis was the most common cause 63%. Out of 84 patients 18 (21%) had complications and surgical site infection was the most postoperative complication 7 (8%). Overall mortality in our study was 2.4% and the duration of hospital stay for ≤ 7 days was 83% and >7 days was 17%. 
The recovery- rate from acute abdominal disease increases in proportion to the earliness of diagnosis and treatment.

Moringa oleifera leaves extract Yemeni was used for green synthesis of copper oxide nanoparticles (CuO). The obtained copper oxide nanoparticles were characterized using ultraviolet–visible spectroscopy (UV–VIS), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and X-ray diffraction (XRD). The aqueous suspension of (CuO NPs) showed a UV-Vis. absorption maxima peaks at 236 and 240 nanometers respectivel primarily in  its formation. The FTIR analysis to be confirmed functional groups of biosynthesized CuO NPs the absorption band at 608cm-1. The XRD analysis revealed that the biosynthesized NPs appear to be more than crystalline of the copper oxide nanoparticles. The characteristic peaks obtained by EDX analysis icon firmed the presence of the element copper (89.8), and the element oxygen (10.2). SEM images show that the particles are round, granular, and nanosized and the nanoparticle has more aggregation ,and conglomeration. Extraction of moringa leaves serves as a promising agent for the balance of particle size. The result of medical value shows significant antibacterial activity.
