Current present-day cataract surgery evolves from a visual restoration to a refractive approach. Greater independence from glasses and improvement of the quality of life were provided after surgery with the appearance of multifocal intraocular lenses (MF-IOLs). Since its creation in the 1980s, MFIOLs has undergone various technical improvements, including trifocal implants and implants with extended depth of vision. Excellent results were achieved thorough preoperative check, including the visual needs of the patients and the inherent eye anatomy. This analysis offers a broad overview of the various types of Mf-IOLs and rules for optimizing results through full preoperative screening and treatment postoperatively complications.

This paper was written to understand if there is a way to identify bullet manufacturer based solely on the shape and characteristics of the bullet. Traditional methods of bullet identification are to use a bullet comparison microscope and look for tool marks and rifling to link it to one particular gun. Cartridge case identification is a lot easier to link to the manufacturer being that there is already some identifying information of the breech face such as the bullet size (9mm), the gun manufacturer (SW-Smith and Wesson), and the trigger pin impression. This research is being done to find an alternative method of bullet identification in the event there are no cartridges left at a crime scene nor does the bullet have sufficient tool marks or rifling to link to a specific gun.

Different types of Glutaredoxins (GRXs) that play a major role in cellular anti-oxidative reactions have been studied for their structure and function from various organisms. Glutathione (GSH), an anti-oxidant with several medical benefits, binds to GRXs. This work has structurally characterized GRX2 from C. reinhardtii (CrGRX2) using biophysical, molecular modelling, and isothermal titration calorimetry (ITC) techniques. CrGRX2 adopts the classical GRX-Trx fold consisting of five β-strands surrounded by four α-helices that bind to GSH with moderate strength through a cysteine residue. The residues involved in the interaction closely match with those observed for E. coli and human counterparts, indicating that the cellular GSH-GRXs antioxidant system is highly conserved.

Dermatofibroma (DF) is a common benign fibrosing lesion that can be found on any surface of the body, most often in the lower extremities. Dermatofibroma that arises on the digits, as in our present case, may be confused with other clinical entities or even malignant tumors, leading to unnecessarily aggressive treatment. To ensure proper diagnosis and treatment, dermatofibroma should be considered in the differential diagnosis of digital papules.

As the coronavirus (COVID-19) pandemic sweeps across the world, it is causing widespread concern, fear and stress, all of which are natural and normal reactions to the changing and uncertain situation that everyone finds themselves in. “The issue facing each and every one of us is how we manage and react to the stressful situation unfolding so rapidly in our lives and communities. Here we can draw on the remarkable powers of strength and cooperation that we also fortunately possess as humans. And that is what we must try to focus on to respond most effectively to this crisis as individuals, family and community members, friends and colleagues,” said Dr Hans Henri P. Kluge, WHO Regional Director for Europe.

It has been identified several factors that can determine the severity and progression of adolescent idiopathic scoliosis (AIS). The natural evolution of this disease has been extensively studied in different populations. However, no practical tool encompasses the main factors determining this disease’s potential progression.

Considering high demand of exploring clean and sustainable source of energy worldwide, biomass derived green bioenergy has tremendous potential. Amongst all possible ways of biomass processing to derive bio-fuels, the biomass pyrolysis is highly preferred thermochemical process that converts the biomass to bio-oil. In our present work, the noncatalytic pyrolysis of ligno-cellulosic biomass samples (sawdust, rice straw and cotton stalk) was successfully carried out using in-house developed fixed bed pyrolytic reactor.

In this work, the dynamic behavior of a wet long bone that has been modeled as transversely isotropic hollow cylinder of crystal class 6 subjected to rotation is investigated. The solution wave for the wave propagation problem is expressed in term of a potential function which satisfies an eight-order partial differential equation, whose solutions lead to the derivation of the explicit solution of the wave equation.

To identify the main risk factors for the progression of adolescent idiopathic scoliosis and to create a tool or classification that helps to identify patients with greater potential for the development of serious scoliosis.

COVID-19 is caused by SARS-CoV-2 and is associated with the increasing number of cases and deaths and has been declared a pandemic by WHO. The treatment strategy focused on preventing the S protein from binding and penetrating the ACE-2 receptor. In addition, S protein-related molecules such as peptides, blockers, and inhibitors that inhibit S protein cleavage are considered candidate therapeutics.

Here we present a case of a 36–year–old woman who suffered from severe (118°) flexion deformity of the right wrist joint because of heavily burn scar contracture of the right hand wrist. After scar excision, the wrist external fixator was applied and adjusted regularly to extent the wrist and to obtain normal range of motion of the wrist joint. Skin reconstruction was performed with a dermal regeneration matrix and eventually with a split-thickness skin graf

The arteriovenous fistula is an anomalous connection between an artery and a vein. The superficial temporal artery and the facial artery are the most affected in the head and neck regions. It can be congenital, acquired or a post-traumatic fistula.

This was a 50-year-old patient with recurrent bilateral nodular anterior scleritis refractory to several treatments, including immunosuppressants and anti Tnfα. She was assessed for the different causes of immune-mediated and infectious diseases, but nothing was found. Tofacitinib was started 5 mg twice a day, which led to the spacing of crises until their total disappearance. At present, the patient has been crisis-free for nine months. In conclusion, the use of Janus Kinase inhibitor (Tofacitinib) alone was effective in the treatment of refractory recurrent nodular anterior scleritis.

Obesity greatly increases the risk of metabolic diseases and preventive approaches for obesity are often insufficient to effectively prevent the diseases. Altering feeding time strategy intervention decreases caloric intake without calorie counting and may be an effective therapy. Therefore, this study investigates the effect of 4-h time restricted feeding on body weight, leptin concentration and lipid profile in healthy non-obese male Wistar rats.

Conveying nanopowder or nanoparticles are involved in the numerous industry fields, but discontinuous and unstable transportation often takes place, and even the pipes clogged because of nanoparticle aggregation. Understanding in detailed the microscopic characteristics of nanoparticles suspended in the base fluid will play a vital role.

Thrombocytopenia is a reduction in the platelet count below the reference range of 150 x 109 /L. It is the second commonest hematologic disorder, following anaemia in pregnancy. Women with thrombocytopenia in pregnancy have a higher tendency to bleed; postpartum haemorrhage is a major cause of maternal mortality in our setting.

Cardiovascular disease (CVD) is one of the most common causes of mortality and morbidity worldwide.Coronary artery disease (CAD) is the most common form of CVD. To prevent CAD we need to assess the risk of future CAD in all patients referred for cardiovascular care, but each of the several available systems for risk assessment has its own limitations. This study was designed to determine whether vitamin D deficiency is a potential risk factor for CAD.

In a cellular environment, if any interruption happened due to the initiation of diseases or disorders in cellular events, it can immediately upset the cellular proceedings, and affect the normal life of the cells and tissues. Vital needs are there to repair the cells and tissues. To regain the normal functioning style of cells and associated cellular environment.

Novel Ni-Re super-alloy catalyst system is found for rapid hydrogenation of toluene to methylcyclohexane (MCH) in a one-pass reactor under mild reaction conditions. The novel bimetallic Ni-Re alloy catalysts exhibit the remarkably enhanced activity and stability for hydrogenation of toluene by comparison with monometallic Ni catalyst. The catalytic performance of novel Ni-Re catalyst is compared with that of Pt catalysts for hydrogenation of toluene. The better activity maintenance of the Ni-Re catalysts than the Pt-based catalysts are found. The alloying effect of Ni with Re is identified by XRD and EXAFS measurements.
