Conversion of caustic red mud (RM, Alumina industry waste) into building materials becoming one of the viable solution for its large scale utilization. The building materials developed using RM often results in efflorescence due to its high alkalinity, which is detrimental for the structural integrity of the buildings. The X-ray shielding tiles developed through ceramic route using the mixtures of RM, BaSO and kaolin clay also suffers from severe NaSO efflorescence when sintered above 1000 °C.

Ulva intestinalis (UI) is widely available edible seaweed and has potential to be introduced as functional food items in Bangladesh. However, potential health hazards of this seaweed with biotoxicity assays and its relation to heavy metal contents were not evaluated previously. With these objectives, toxic effects of UI collected from floating raft culture in Monkhali Beach was evaluated using various organisms such as Chlorella vulgaris, Artemia salina, Daphnia magna, and Lactuca sativa.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease marked by chronic inflammation and tissue damage that impacts multiple organ systems and diminishes the quality of life. Among the frequent comorbidities in SLE, thyroid dysfunction, including hypothyroidism and hyperthyroidism, stands out due to its high prevalence and common autoimmune basis. This review examines the epidemiological, genetic, and immunological factors that link SLE with autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease.

Glyphosate [N-(phosphonomethyl) glycine], a systemic herbicide, is used globally (825 million kg/year) in 750+ formulations. The International Agency for Research on Cancer classified glyphosate is a probable human carcinogen (Group 2A), but epidemiological studies have been lacking for its association with liver cancer and chronic liver disease. We analyzed urine specimens from 591 patients with newly diagnosed liver cancer, chronic liver disease (CLD), and healthy individuals from five different medical centers between 2011 to 2016 in Thailand.

Pancreatitis is an inflammatory disease of the pancreas that can arise due to various factors, including environmental risks such as diet, alcohol, and smoking, as well as genetic predispositions. In some cases, pancreatitis may progress and become chronic, leading to irreversible damage and impaired pancreatic function. Genome-wide association studies (GWAS) have identified polymorphisms at the X-linked locus as risk factors for both sporadic and alcohol-related chronic pancreatitis.

Perfluorooctanoic acid "Forever Chemical" presents substantial ecological challenges owing to its persistence and resistance to degradation. The study introduces a novel approach by integrating ternary metal oxides-GdO, CoO, and BiO with carbon nanotubes to develop a versatile electrode material, CNT@GdCoBi NCs, which demonstrates dual functionality as both an electrochemical sensor for PFOA and a component for energy storage devices. The electrode exhibits outstanding electrochemical sensing performance, with a detection limit for PFOA of 4.

Purpose: To report the visual outcomes and complications in eyes with retained lens fragments (RLF) following cataract surgery undergoing pars plana lensectomy (PPL) and scleral-fixated intraocular lens insertion (SFIOL).

Methods: Patients with RLF who underwent pars plana vitrectomy (PPV), PPL, and SFIOL insertion from January 2015 to December 2022 were included. The visual acuity (VA) outcomes and complication rates were compared between those receiving sutured versus sutureless SFIOL insertion as well as those undergoing SFIOL insertion at the time of PPV and PPL versus those undergoing SFIOL insertion during a subsequent surgery.

Hypertension is a prevalent health concern with significant implications for cardiovascular disease risk, affecting diverse populations worldwide and imposing substantial health system burdens. This review article explores racial and ethnic disparities in hypertension prevalence, treatment, and management, highlighting the disproportionate impact on minority populations. Certain racial and ethnic groups in the United States exhibit higher prevalence rates of hypertension and related complications due to a confluence of genetic, social, and economic factors.

Article Synopsis
  • The greater palatine canal (GPC) is crucial for accessing the maxillary division of the trigeminal nerve, but anatomical variations can complicate surgeries in this area, necessitating a clear understanding of both normal and anomalous anatomy.
  • This study aims to investigate the GPC's bony structure in 30 dried skull specimens to identify anatomical variations and improve existing knowledge, which is often inconsistent and lacks detail.
  • By systematically documenting these variations, the research seeks to enhance clinical understanding, minimize surgical complications, and emphasize the importance of further studies in this area.

The study examines export impact of Pakistan's integration into Shanghai Cooperation Organization (SCO) on its export's performance. We apply Poisson Pseudo-Maximum Likelihood (PPML) on augmented gravity model to estimate trade data from the period before and after permanent membership with Shanghai Cooperation Organization in 2017. The study aims to explore changes in exports volume and analyze the key mechanism through which Shanghai Cooperation Organization promotes exports.
