- A new guideline: 'Intoxication: initial approach in the hospital' will be published this year. This guideline sets out the latest insights on gastrointestinal decontamination in intoxication; the advice is summarized in a flowchart.- The advice is to generally administer activated charcoal, unless there are indications that the toxin will not bind to activated charcoal or that the amount of toxin that the patient has ingested is too great; in these cases gastric lavage can be considered.- Activated charcoal can be administered up to 2 hours after the ingestion of a toxic substance, unless there are contra-indications...

A five-year field experiment was conducted to investigate the effects of straw application on nitrate leaching loss. Treatments included soil that was not treated (control), soil treated with straw at a low rate (4,500 kg ha-2, T1) and soil treated with straw at a high rate (9,000 kg ha-2, T2). Nitrate-nitrogen leaching in the 10, 20, 30, 60, and 90 cm soil layers was measured using the resin-core method. The results indicated that straw application could reduce soil nitrate leaching losses in the 0-30 cm layer...

BACKGROUND: Although gunshot-induced extremity fractures are typically not considered open fractures, there is controversy regarding wound management in the setting of operative fixation to limit infection complications. Previous studies have evaluated the need for a formal irrigation and debridement (I&D) prior to intra-medullary nailing (IMN) of gunshot-induced femur fractures but none have specifically evaluated tibias. By comparing primary IMN for tibial shaft fractures caused by low-velocity firearms additionally treated with a formal operative I&D (group 1) with those without an I&D (group 2), we sought to identify whether there are: differences in treatment group infection rates; particular fracture patterns more prone to infection; and patient characteristics more prone to infections...

The global magnitude (Pg) of soil organic carbon (SOC) is 677 to 0.3-m, 993 to 0.5-m, and 1505 to 1-m depth. Thus, ~55% of SOC to 1-m lies below 0.3-m depth. Soils of agroecosystems are depleted of their SOC stock and have a low use efficiency of inputs of agronomic yield. This review is a collation and synthesis of articles published in peer-reviewed journals. The rates of SOC sequestration are scaled up to the global level by linear extrapolation. Soil C sink capacity depends on depth, clay content and mineralogy, plant available water holding capacity, nutrient reserves, landscape position, and the antecedent SOC stock...

BACKGROUND: Intersphincter resection (ISR) is considered to be a superior technique offering sphincter preservation in patients with ultralow rectal cancer.1 Because high-definition laparoscopy offers wider and clearer vision into the narrow pelvic cavity and intersphincteric space, ISR has been further refined.2 However, functional outcome after ISR has not been optimal. More than half of patients receiving ISR suffer partial or even complete anal incontinence.3 We therefore propose a laparoscopic-assisted modified ISR, with the aim of improving sphincter function following ISR...

Urease inhibitors and nitrification inhibitors can reduce nitrogen (N) loss in agriculture soil. However, the effect of inhibitors on soil N2O emissions under the drip irrigation system remains unclear. A pot and a field experiment with two inhibitors were conducted to explore how inhibitors regulate soil nitrogen transformation and N2O emissions. In the pot experiment, three treatments included control, urea, and urea + N-(n-butyl)thiophosphoric triamide (NBPT, urease inhibitor). In the field experiment, three treatments included control, urea, and urea + NBPT + 2-chloro-6-(trichloromethyl)pyridine (nitrapyrin, nitrification inhibitor)...

Brewing industry releases large quantities of wastewater after product generation. Brewery wastewater contains organic compounds which are biodegradable in nature. These biodegradable wastes can be recycled and reused and hence considered as suitable products for agriculture. But before using wastewater for agriculture, it is better to evaluate the phytotoxic effects of wastewater on crops. Hence, the main objective of this study is to evaluate the effects of brewery effluent on seed germination and growth parameters of selected crop species like chickpea (Cicer arietinum), maize (Zea mays), and pigeon pea (Cajanus cajan)...

PURPOSE: Implant-supported dental prostheses are based on the principle of osseointegration, and the success of dental implantation depends on adequate formation of this intimate bone-to-implant contact. The application of heat during the drilling procedure leads to a rise in intraosseous temperature at the prospective implant site, which may result in various complications. The purpose of the present study was to compare the ability of thermocouples and infrared thermography to detect changes in intraosseous temperature during dental implant site preparation...

This paper presents a hydrodissection technique performed with high-speed pulse injection of only 0.1 cc liquid and assess its efficacy, safety, and the level of reduction in posterior capsule rupture complications in phacoemulsification cataract surgery. The kinetic energy of moving objects is directly proportional to the mass and to the square of its velocity. The high energy obtained by high-speed pulse injection of a small amount of liquid ensures highly effective dissection. Since the amount of liquid is very small, the increase in intraocular pressure and the risk of rupture in the posterior capsule due to anterior capsular block are greatly reduced...

INTRODUCTION: Contracted endodontic cavities (CECs) have developed from the concept of minimally invasive dentistry and provide an alternative to traditional endodontic cavities (TECs). They have been designed in an effort to preserve the mechanical stability of teeth. The contracted cavity design preserves more of the dentin but may influence the geometric shaping parameters. The aim of this micro-computed tomographic study was to evaluate the influence of contracted endodontic cavities on the preservation of the original root canal anatomy after shaping with nickel-titanium rotary instruments...
