Human papillomavirus (HPV)-associated sinonasal squamous cell carcinoma (SNSCC) (HPV+ SNSCC) is a recently recognized entity that accounts for up to one-third of SNSCC. Although at present these cancers are not routinely tested for HPV, the incidence is increasing and HPV+ SNSCC is associated with superior survival outcomes compared with HPV- SNSCC. Here, we present the case of a patient with HPV+ SNSCC treated with endoscopic resection followed by postoperative radiation and review the literature summarizing epidemiology and management of this disease, with emphasis on the importance of HPV testing in SNSCC.

A sustainable biosorbent, silver nanoparticles-decorated coffee-ground waste (CWAg), was synthesized through a simple in-situ reduction method. CWAg is extensively characterized via SEM-EDX, PZC, FTIR, XRD, HR-TEM, and XPS analyses. The biosorbent was tested to remove chromium (Cr(VI)) and methylene blue (MB) from wastewater, and its antibacterial properties was evaluated.

This research aims to investigate A novel and complete system consists of hybrid renewable energy farm with high-energy-consuming seawater desalination in fourth locations in Egypt. This paper proposes fuzzy-based multi-criteria decision-making model for optimal sizing of a hybrid PV/Wind/Storage system to power the reverse osmosis (RO) desalination process in order to increase freshwater availability and meet the electric load requirement in selected area. Firstly, according to collected data and cost of electricity (COE) for various renewable energy resources, specific procedures to determining the optimal system design and optimal sizing (solar cell, wind turbine parameter and storage system units) are presented for selected site.

Objective: There is persistent debate in the literature surrounding the true predictors of biochemical remission after resection of somatotroph adenoma. A multimodal analysis of a large number of patients is needed to better understand which patients may be at higher or lower risk for remission failure after surgery.

Methods: A retrospective review was performed on patients undergoing somatotroph adenoma resection.

Background: Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a minimally invasive technique for treating gastric outlet obstruction (GOO). The aim of this study was to assess the outcomes of EUS-GE in managing benign GOO caused by duodenal stenosis in patients with acute pancreatitis.

Methods: This international retrospective study analyzed patients treated with EUS-GE for GOO caused by acute pancreatitis until December 2023, evaluating technical and clinical success, adverse events, and reintervention.

Article Synopsis
  • There is currently no reliable intraoperative method to predict visual outcomes after endoscopic endonasal surgery (EES), prompting the need for better assessment tools during surgery.
  • The study investigated the use of intraoperative indocyanine green (ICG) angiography to evaluate blood flow to the optic chiasm and its connection to postoperative visual function.
  • The results indicated that the absence of ICG fluorescence within 10 seconds after ICG injection was significantly linked to new visual deficits post-surgery, highlighting potential ischemic changes in the optic chiasm.

Article Synopsis
  • - The study investigates the protective effects of astaxanthin (ASX) against heart damage caused by isoproterenol (ISO) in rats, focusing on its role in enhancing mitochondrial biogenesis.
  • - Rats were divided into groups, with one receiving ISO to induce heart damage and others supplemented with varying doses of ASX before ISO administration, showing ASX lowered key cardiac injury markers and improved antioxidant levels.
  • - Findings suggest that astaxanthin helps mitigate oxidative stress and cardiac cell death from ISO exposure by increasing mitochondrial function and reducing harmful compounds, indicating its potential as a therapeutic agent for heart protection.

Aluminum oxide nanoparticles (AlO NPs) are among the most extensively utilized nanoparticles in nanotechnology and that have negative impacts on the environment. Therefore, the intention of this work is to investigate the protective and therapeutic effects of curcumin in nanoform (Cur NPs) against AlO NPs induced kidney toxicity, oxidative stress, DNA damage, and changes in necrosis factor alpha (TNFα) and proliferating cell nuclear antigen (PCNA) expressions in male rats. Fifty healthy adult male were divided into five groups [G1, control; G2, received 50 mg/kg/day for 4 weeks of Cur NPs orally; G3, received 6 mg/kg BW orally for 4 weeks of AlO NPs; G4, (Cur NPs + AlO NPs) received Cur NPs and AlO NPs at a dose similar to G2 and G3, respectively for 4 weeks; G5, (AlO NPs + Cur NPs) received AlO NPs at a dose similar to G3 for 4 weeks then received Cur NPs at a dose similar to G2 for another 4 weeks].

In order to protect the copper against corrosion, a novel corrosion inhibitor known as diphenyl ((2-aminoethyl) amino) (4-methoxyphenyl) methyl) phosphonate (DAMP) was developed. Acid solutions of HCl and HSO were the aggressive solutions employed in this study. Analysis using the FT-IR, H-NMR, P-NMR, C-NMR and BET confirmed that the DAMP was successfully synthesized.

Objectives To evaluate and compare different polygenic risk score (PRS) models in predicting Parkinsons disease (PD) across diverse ancestries, focusing on identifying the most suitable approach for each population and potentially contributing to equitable advancements in precision medicine. Methods We constructed a total of 105 PRS across individual level data from seven diverse ancestries. First, a cross-ancestry conventional PRS comparison was implemented by utilizing the 90 known European risk loci with weighted effects from four independent summary statistics including European, East Asian, Latino/Admixed American, and African/Admixed.
