Raman spectroscopy and photoluminescence study of PN junction p-graphene/n-GaAs.

Single layer graphene (SLG) was synthesized via high-quality chemical vapor deposition (CVD) on high-quality copper and subsequently transferred onto SiO2 and on n-GaAs substrates with varying doping electron concentrations (n = 1016, 1017, 5 × 1017, 1018, and 5 × 1018 cm-3). The n-GaAs substrates were grown by molecular beam epitaxy. The optical properties of the SLG were investigated through photoluminescence (PL) and Raman spectroscopy measurements.

Incidence of the Mucopolysaccharidoses in Tunisia, 1999 - 2021.

Background: This cross-sectional study aimed to describe and discuss the epidemiology of mucopolysaccharidoses (MPS) in Tunisia.

Methods: Patients diagnosed with a MPS disorder in two referral laboratories in Tunisia between 1999 and 2021 were included. Diagnosis was based on clinical and radiological features and analysis of urinary glycosaminoglycans, and enzyme assay in some of the patients.

Bioaugmentation and phytoremediation wastewater treatment process as a viable alternative for pesticides removal: case of pentachlorophenol.

Unlabelled: This study focused on the potential for pentachlorophenol removal by a biological process in secondary treated wastewater (STWW). The proposed process is a combined method of phytoremediation using a native plant, Polypogon maritimus and Lemna minor, and bioaugmentation using a fungus. The bioaugmentation process was performed by a fungal isolate capable of removing PCP, isolated from the compost.

SMAD3, Cell proliferation and lymph nodes metastasis in breast cancer hormone-dependent.

Introduction: Tumor Growth Factor-β (TGF-β) is a multifunctional cytokine that plays a crucial role in various biological processes. TGF-β is also involved in various pathologies including breast cancer (BC). BC is strongly dependent on hormone receptors such as Estrogen receptors (ERa, ERb) and Progesterone Receptor (PR).

Segmental renal vein thrombosis: An unusual complication of acute pyelonephritis.

Renal vein thrombosis is not a common manifestation in the context of acute pyelonephritis. We report the case of a 29-year-old female diabetic patient that was admitted to our department for an episode of complicated acute pyelonephritis. Initial imaging showed a left lower polar abscess of 27 mm and urine cultures grew community acquired K.

Pelvic leiomyoma associated with intermediate risk prostate cancer: A case report.

Pelvic leiomyoma in male patients is a very rare occurrence and its association with prostate cancer is a unique clinical situation. This study reports a new case of a 9 cm pelvic Leiomyoma associated with intermediate-risk localized prostate cancer in a 68-year-old patient. The leiomyoma was discovered fortuitously after an MRI was performed in the context of prostate cancer work-up.

Bilateral renal hydatid disease associated with complex urolithiasis: A case report.

Introduction And Importance: The association of bilateral renal hydatid cysts and complex urolithiasis is unprecedented. We herein report the case of a patient presenting with both diseases.

Case Presentation: A 56-year-old female patient with a history of chronic kidney disease presented with right flank pain.

The effect of using fresh farmyard manure (animal manure) on the severity of in soil, root, stem, and kernels as well as lodging and borer incidence of maize plants.

, an important maize pathogen, produce fumonisins, causes stalk rot and consequentially reduce crop growth and yield. Therefore, herein we aimed to evaluate the potential use of two farmyard soil organic manures, i.e.

STAT-5 and STAT-6 in Breast Cancer: Potential Crosstalk With Estrogen and Progesterone Receptors Can Affect Cell Proliferation and Metastasis.

Background: Signal transducers and activators of transcription 5a and 6 (STAT5a and STAT6) play a critical role in tumorigenesis of mammary glands. Based on previous studies, the breast cancer is largely dependent on hormone receptors. Consequently, it is very interesting to decipher the relationship between the STAT5a and STAT6 expression and the molecular distribution of estrogen receptors (ERs) and progesterone receptors (PRs) in mammary tumors.

Inhibitor Assessment against the LpxC Enzyme of Antibiotic-resistant Acinetobacter baumannii Using Virtual Screening, Dynamics Simulation, and in vitro Assays.

Background: Bacterial resistance is currently a significant global public health problem. Acinetobacter baumannii has been ranked in the list of the World Health Organization as the most critical and priority pathogen for which new antibiotics are urgently needed. In this context, computational methods play a central role in the modern drug discovery process.

Biological and Molecular Characterization of the Lytic Bacteriophage SoKa against pv. , Causal Agent of Citrus Blast and Black Pit in Tunisia.

pv. (Pss), the causal agent of citrus blast and black pit lesion of lemon fruit, continues to cause serious damage in citrus production in Tunisia. Faced with the rapid emergence of the disease and the inefficiency of conventional control methods, an alternative strategy based on the use of bacteriophages was pursued in this study.

Epiphytic Yeasts and Bacteria as Candidate Biocontrol Agents of Green and Blue Molds of Citrus Fruits.

Regional techniques for pain management following laparoscopic elective colonic resection: A systematic review.

Introduction: Pain management is an integral part of Enhanced Recovery After Surgery (ERAS) following laparoscopic colonic resection. A variety of regional and neuraxial techniques were proposed, but their efficacy is still controversial. This systematic review evaluates published evidence on analgesic techniques and their impact on postoperative analgesia and recovery for laparoscopic colonic surgery patients.

The flavonoid, kaempferol-3-O-apiofuranosyl-7-O-rhamnopyranosyl, as a potential therapeutic agent for breast cancer with a promoting effect on ovarian function.

It is widely known that breast cancer cells eventually develop resistance to hormonal drugs and chemotherapies, which often compromise fertility. This study aimed to investigate the effect of the flavonoid, kaempferol-3-O-apiofuranosyl-7-O-rhamnopyranosyl (KARP), on 1) the viability of MCF-7 breast cancer cells and 2) ovarian function in rats. A dose-dependent decrease in MCF-7 cell survival was observed, and the IC50 value was found to be 48 μg/ml.
