(Linnaeus, 1758) as a Sentinel Species to Assess Trace Metal Occurrence: A Case Study of Kuwait Waters (Northwestern Arabian Gulf).

Heavy metal pollution can adversely impact marine life, such as crabs, which can accumulate it in different organs and potentially transfer and biomagnify along the food chain in aquatic ecosystems. This study aimed to examine the concentrations of heavy metals (Cd, Cu, Pb, and Zn) in sediment, water, and crab tissues (gills, hepatopancreas, and carapace) of the blue swimmer crab in the coastal areas of Kuwait, northwestern Arabian Gulf. Samples were collected from Shuwaikh Port, Shuaiba Port, and Al-Khiran areas.

Recent advances in anaesthesia for intrauterine and foetal surgery.

Advances in prenatal diagnostic techniques have enabled early detection of potentially correctable foetal anomalies. Here, we summarise recent developments in anaesthesia for foetal surgery. Types of foetal surgery include minimally invasive, open mid-gestational and ex-utero intrapartum treatment (EXIT) procedures.

In sickness and in debt: The COVID-19 impact on sovereign credit risk.

The COVID-19 pandemic provides a unique setting in which to evaluate the importance of a country's fiscal capacity in explaining the relation between economic growth shocks and sovereign default risk. For a sample of 30 developed countries, we find a positive and significant sensitivity of sovereign default risk to the intensity of the virus's spread for fiscally constrained governments. Supporting the fiscal channel, we confirm the results for Eurozone countries and U.

Waves on Louisiana Continental Shelf Influenced by Atmospheric Fronts.

Ocean-atmospheric dynamical processes influence the wave characteristics, and sea surface temperature (SST). The processes that affect SST in the ocean area included surface heat fluxes, wind, and precipitation. In this study, we analyzed the wave data in response to the cold front passages over Louisiana continental shelf.

Honey Dressing Accelerates Split-Thickness Skin Graft Donor Site Healing.

The management of the donor site after harvesting a skin graft is an important issue, as patients often report more discomfort at the donor site than at the recipient site. There is, however, a plethora of dressings available for the treatment and management of donor sites, yet, there is no widely accepted method established for these partial thickness wounds. Honey has been found to be useful in the treatment of burns and other wounds, split-thickness skin graft donor sites are like partial thickness burn wounds and honey's healing effect on burn wound can also be expected on these types of wounds.

Safety features in anaesthesia machine.

Anaesthesia is one of the few sub-specialties of medicine, which has quickly adapted technology to improve patient safety.

The present study evaluates effectiveness of different concentrations of Sufentanil mixed in propofol for TIVA in laparoscopic cholecystectomy. Sixty adult patients of ASA physical status I or II (randomly divided into 3 groups of twenty each) undergoing elective laparoscopic cholecystectomy were included in this randomised control study.

Critical care issues in adult liver transplantation.

Over the last decade, liver transplantation has become an operational reality in our part of the world. As a result, clinicians working in an intensive care unit are more likely to be exposed to these patients in the immediate postoperative period, and thus, it is important that they have a working knowledge of the common complications, when they are likely to occur, and how to deal with them. The main focus of this review is to address the variety of critical care issues in liver transplant recipients and to impress upon the need to provide favorable circumstances for the new liver to start functioning and maintain the function of other organs to aid in this process.

TiO2 supported over porous silica photocatalysts for pesticide degradation using solar light: Part 2. Silica prepared using acrylic acid emulsion.

An acrylic acid emulsion mixture is used for synthesis of novel porous silica (E-Si) material.
