Effect of In-vitro Loading on Equine Carpi of Different Morphology: A Pilot Study

2025-04-16T19:27:26+00:00

Equine carpal morphology is fundamental when considering the joint stability and soundness. Although specific preferable and poor carpal conformations have been identified, it is as yet unclear how such varied carpal conformations respond to loading. This pilot study aimed to investigate the effects of in-vitro loading on carpal joints that had different bone conformations. Two carpi were selected; a carpus of a Warmblood horse (H1) with a favourable carpal conformation and a carpus of a Thoroughbred (H2) with a morphology associated with carpal pathology. Specimens were subjected to mechanical loading via an Instron test machine and dorsopalmar radiographs were taken before and after loading. Five carpal angular parameters were measured on the radiographs to assess changes in the morphometry of the carpi. The results indicated that H2 experienced greater changes in angular values, particularly in the angle of the radial facet of the third carpal bone (Rf.C3-Prx.Mc3), and instability under load. Conversely, H1 demonstrated a consistent stability, with minimal changes in the measured angles. The findings emphasize the important role of specific carpal morphology especially the angle of the radial facet of the third carpal bone in the joint stability which may be important in minimizing the risk of injury during high-speed racing.

Green Synthesis of Silver Nanoparticles and their Antibacterial Activity Enhancement

In this study, a green, facile method was implemented for the synthesis of silver nanoparticles (AgNPs). The effect of pH, temperature, content of sage extract, ionic solution concentration, and reaction time was investigated using aqueous extract of Salvia officinalis as a bioreducing and capping agent in a single step biosynthesis. All these factors showed a significant influence on the synthesis rate, size and shape of the AgNPs. The optimum synthesis conditions were at pH 10, 10mM [Ag+], 5 days reaction time, 2:5 volume ratio extract: [Ag+] and 60°C. The prepared silver nanoparticles were characterized using UV-Vis, scanning electron microscopy (SEM), FTIR and X-Ray Diffraction. According to the observed results, the synthesized AgNPs were confirmed and showed a spherical morphology and a particle size of 30.9 nm. Furthermore, the AgNPs showed significant antibacterial activity against gram-positive and gram-negative bacteria and enhancement for antibiotic activity. Further research is needed to develop more this approach and to investigate the effects of AgNPs.

Demographic and Clinical Characteristics of Breast Cancer at the National Cancer Center in Benghazi

2025-06-12T17:55:11+00:00

Background: Breast cancer ranks among the top five cancers in Libya, with incidence rates varying globally and generally lower in African countries such as Libya and Nigeria. Aim: This study aimed to characterize the demographic and clinical profiles of breast cancer patients treated at the Oncology Department of the National Cancer Center in Benghazi, Libya. Methods: A retrospective cross-sectional study was conducted at the aforementioned department from February to August 2024. The study included 100 patients. Patients’ data were extracted from medical records and analyzed using Microsoft Excel 2016. Results: The study patients comprised predominantly Libyan females, with a mean age of 55.4 years. Most patients (98%) were non-smokers and diabetes was the most frequently reported comorbidity. Nearly half (49%) of patients had no family history of breast cancer. Invasive ductal carcinoma was the predominant tumor type. Surgical treatment was the primary modality, frequently combined with chemotherapy and radiotherapy. Conclusion: The breast cancer patient population in this study was mainly female with an average age of 55.4 years. The high prevalence of diabetes underscores potential lifestyle influences on breast cancer risk. The absence of family history in nearly half of the cases emphasizes the importance of broad-based awareness and screening programs.
