UK Foot and Ankle Thromboembolism (UK-FATE).

Aims: Venous thromboembolism (VTE) is a potential complication of foot and ankle surgery. There is a lack of agreement on contributing risk factors and chemical prophylaxis requirements. The primary outcome of this study was to analyze the 90-day incidence of symptomatic VTE and VTE-related mortality in patients undergoing foot and ankle surgery and Achilles tendon (TA) rupture.

Design and control of jumping microrobots with torque reversal latches.

Jumping microrobots and insects power their impressive leaps through systems of springs and latches. Using springs and latches, rather than motors or muscles, as actuators to power jumps imposes new challenges on controlling the performance of the jump. In this paper, we show how tuning the motor and spring relative to one another in a torque reversal latch can lead to an ability to control jump output, producing either tuneable (variable) or stereotyped jumps.

Zinc-Substituted Cobalt Phosphate [ZnCo(PO)] as a Bifunctional Electrocatalyst.

Development of highly efficient, earth-abundant, and stable bifunctional electrocatalysts is pivotal for designing viable next-generation metal-air batteries. Cobalt-based phosphates provide a treasure house to design electrocatalysts, with a wide range of cation substitutions to further enhance their electrocatalytic activity. In particular, phosphates with distorted geometry show favorable binding efficiency toward water molecules with low overpotential.

Delivering surgical education: a specialist surgical society and undergraduate student collaboration.

Currently, the delivery of the undergraduate medical curriculum includes various teaching, learning and assessment strategies. Self-directed learning is an important aspect of this mix and includes the use of resources, sometimes not provided by the parent University, in the student's own time to enhance the student's knowledge, skills and professional practice. Societies aimed at a particular specialty contain a pool of professionals that can provide undergraduate students with opportunities for further self-directed learning, development of specialty-specific core skills and exploration of research interests.

Toxicity assessment of common acaricides and mineral oils on Anagyrus vladimiri, an effective biocontrol agent of citrus mealybug.

Chemical pesticides, while playing an important role in the suppression of insect pests, should be used in a manner that minimizes negative effects on natural enemies. The parasitoid, Anagyrus vladimiri Triapitsyn (Hymenoptera: Encyrtidae), plays an important role in the management of mealybug pests of citrus groves in the Mediterranean region. This study was conducted to evaluate the effect of commonly used acaricides (Spirodiclofen, Spirotetramat, Sulfur, Fenpyroximate, Abamectin) and mineral oils (Levanola, EOS, JMS, and Ultrapaz) on acute mortality of A.

First principles investigation of anionic redox in bisulfate lithium battery cathodes.

The search for an alternative high-voltage polyanionic cathode material for Li-ion batteries is vital to improve the energy densities beyond the state-of-the-art, where sulfate frameworks form an important class of high-voltage cathode materials due to the strong inductive effect of the S ion. Here, we have investigated the mechanism of cationic and/or anionic redox in LiM(SO) frameworks (M = Mn, Fe, Co, and Ni and 0 ≤ ≤ 2) using density functional calculations. Specifically, we have used a combination of Hubbard corrected strongly constrained and appropriately normed (SCAN+) and generalized gradient approximation (GGA+) functionals to explore the thermodynamic (polymorph stability), electrochemical (intercalation voltage), geometric (bond lengths), and electronic (band gaps, magnetic moments, charge populations, ) properties of the bisulfate frameworks considered.

Pyrophosphate NaCoPO Polymorphs as Efficient Bifunctional Oxygen Electrocatalysts for Zinc-Air Batteries.

Developing earth-abundant low-cost bifunctional oxygen electrocatalysts is a key approach to realizing efficient energy storage and conversion. By exploring Co-based sodium battery materials, here we have unveiled nanostructured pyrophosphate NaCoPO polymorphs displaying efficient bifunctional electrocatalytic activity. While the orthorhombic polymorph (-NCPy) has superior oxygen evolution reaction (OER) activity, the triclinic polymorph (-NCPy) delivers better oxygen reduction reaction (ORR) activity.

Facile synthesis and phase stability of Cu-based NaCu(SO)·HO ( = 0-2) sulfate minerals as conversion type battery electrodes.

Mineral exploration forms a key approach for unveiling functional battery electrode materials. The synthetic preparation of naturally found minerals and their derivatives can aid in designing of new electrodes. Herein, saranchinaite NaCu(SO) and its hydrated derivative kröhnkite NaCu(SO)·2HO bisulfate minerals have been prepared using a facile spray drying route for the first time.

An overview of hydroxy-based polyanionic cathode insertion materials for metal-ion batteries.

Rechargeable batteries based on Li-ion and post Li-ion chemistry have come a long way since their inception in the early 1980s. The last four decades have witnessed steady development and discovery of myriads of cathode materials taking into account their processing, economy, and performance along with ecological sustainability. Though oxides rule the battery sector with their high energy and power density, polyanionic insertion compounds work as gold mines for designing insertion compounds with rich structural diversity leading to tuneable redox potential coupled with high structural/chemical/thermal stability.

Crystal and Magnetic Structures of Monoclinic FeOHSO.

The crystal and magnetic structures and properties of the monoclinic form of the iron hydroxysulfate FeOHSO were investigated by magnetometry and neutron powder diffraction. The space group 2/ was confirmed, and the proton position was located close to that predicted by calculations. The collinear antiferromagnetic (0,0,0) structure forming below the Néel temperature ∼ 125 K is described by the 2'/' (No.

Mild mitochondrial uncoupling protects from ionizing radiation induced cell death by attenuating oxidative stress and mitochondrial damage.

Ionizing radiation (IR) induced mitochondrial dysfunction is associated with enhanced radiation stimulated metabolic oxidative stress that interacts randomly with intracellular bio-macromolecules causing lethal cellular injury and cell death. Since mild mitochondrial uncoupling emerged as a valuable therapeutic approach by regulating oxidative stress in most prevalent human diseases including ageing, ischemic reperfusion injury, and neurodegeneration with comparable features of IR inflicted mitochondrial damage. Therefore, we explored whether mitochondrial uncoupling could also protect from IR induced cytotoxic insult.

Retrospective Analysis of Arthrodesis from Various Options after Anterior Cervical Discectomy.

Introduction: Anterior cervical discectomy is a surgical procedure performed to treat a herniated/degenerated disc in the cervical region. There have been various studies comparing arthrodesis rates among various procedures. Our patients belonged to varied socioeconomic background and underwent anterior cervical microdiscectomy without/with instrumentation.

Plasticity in reproductive output and development in response to thermal variation in ladybird beetle, Menochilus sexmaculatus.

All organisms are exposed to daily as well as seasonal variation in temperature in nature. However, ectotherms are strongly affected by temperature and its variations. Most laboratory studies on effect of temperature on life history traits employ constant instead of fluctuating temperature regimes, though the latter is more reflective of nature.
