To adapt the perfusion-CT (PCT) examination-protocol in patients with liver cirrhosis and suspected hepatocellular carcinoma (HCC) while keeping diagnostic accuracy and qualitative assessment of tumor enhancement patterns (wash-in/wash-out) at comparable radiation dose.

The aim of this study was to investigate the safety and feasibility of common carotid artery sympathetic nerve network stripping (CCASNS) combined with implanted vagus nerve stimulation (iVNS) for seizure control in children with cerebral palsy with refractory epilepsy. We reviewed the medical records of children with cerebral palsy with drugrefractory epilepsy treated at the Fifth Affiliated Hospital of Zhengzhou University from September 2015 to June 2019.

The study was aimed to standardize pro-inflammatory cytokines and haematological biomarker level in visually adult healthy swine as an early health check-up scanner. In the present study, total six (6) crossbreed pigs (Yorkshire × Swedish Landrace) with similar age group (3 years) and unisex (male) with average body wt (140 kg) were selected for sampling.

SiO2/Si substrates were modified by physical and chemical treatments in order to improve adhesion and homogeneity of segregated graphene. The objective of this work was to decrease defects concentration in graphene crystallites in segregated graphene. It was done by chemical and physical treatment of the SiO2 substrate prior to deposition of catalytic nickel layer.

Obesity is considered a serious health hazard. It predisposes the individual to many disorders, such as diabetes and heart disease, it shortens the life span, and it complicates childbirth and surgery. This study was a cross-sectional study conducted in health centers at Khartoum locality during November 2018- January 2019; aimed to predict mortality among a young female Sudanese population enrolled in health centers.

The risk of overweight and/ or obesity is one of the increasing conditions worldwide touching both the developed and developing countries. It is becoming much devastating specially in town population. The aim of this study was to assess the prevalence of overweight/obesity and the associated risk factors among adults residing in the selected towns of western part of Ethiopia.

Feeding mice a diet containing high fat and high sucrose has been promoted as a good model for type 2 diabetes. This study sought to determine the effect of feeding mice a high fat and high sucrose diet on neuropathy compared to mice fed only a high fat diet and mice fed a high diet and treated with streptozotocin.

In contrast to previous years which consistently had an influenza “season” our clinical virology laboratory has made only a strikingly small number of identifications of influenza during the early weeks of this respiratory virus season. This experience is similar to its decreased activity in the Southern Hemisphere during their winter, April to July 2020. We report the same experience with RSV. These results are likely attributable to measures employed for control of COVID-19, including social distancing and the use of face masks.

The classical Fisher exact test [1], which is unconditionally the uniformly most powerful unbiased (UMPU) test, requires randomization at the critical value(s) to be of size α. Obviously, one needs a non-randomized version of this. Rejecting the null only if the test-statistic’s outcome is more extreme than the critical values, reduces the actual size considerably. The modified Fisher exact test introduced in [2] additionally rejects the null when the test attains the critical value c(t) and the randomization probability γ(t) (that depend on the total number of successes T) exceeds a threshold γ0, which is determined such that, for all values of the nuisance parameter, the size of the unconditional modified test is smaller, but as close as possible to α. This greatly improves the size and power of the test as compared to, for example, the conservative nonrandomized Fisher exact test, while controlling the Type 1 error rate.

The victims of intimate partner violence are subjected to emotional, physical and/or sexual abuse. The physical abuse often includes episodes of mechanical asphyxia and its most frequent mechanisms: throttling and strangulation. Non-fatal asphyxia situations have signs, symptoms and short-term or long-term consequences whose severity varies according to the intensity, duration and number of episodes.

The emergence of SARS-CoV-2 variants raises increasing concerns about the efficacy of currently available vaccines [1]. mRNA vaccines (BNT162b2, Pfizer-BioNTech; mRNA-1273, Moderna) are developed based on one specific part of the viral genome to elicit immune response. Therefore, they might be susceptible to immune escape mutations, such as the ones in the viral Spike protein [2].

Lyme neuroborreliosis (LNB) is a rare infectious disorder of the nervous system caused by Borrelia burgdorferi spirochetes. Different neurological conditions were reported in the disease.

Cassava processing is a year-round activity in Nigeria, especially in southern part and Ibadan city. The wastes generated by the various processing industries are enormous. Cassava peels are a major residue of processing to prepare various food products. The cassava peels have high concentration of cyanide which has toxic and polluting effects. It is therefore important that the peels are properly processed or pre-treated to reduce the cyanide content before using them as livestock feed which is a common practice among livestock rearers.

Various interventions have been investigated for the purpose of regaining the limited ADL of chronic stroke hemiplegia. However the application of intervention depending on motor function is still unclear.

To apply fertilizer rationally during promotion of Zhongjiao No.9 being a fusarium wilt resistant new variety, dry matter (DM) and NPK in four organs of the banana were tested. Average fresh and dry weight (FW and DW) of No.9 were 145.35±6.42 and 18.18± 0.70 kg plant-1.

WLAN (wireless local area network) is used as an important worldwide communication-technique. By this, always there is an electromagnetic field exposure. In contrast to the ICNIRP-safety guidelines, whereby no bioeffect is possible by these low-energetic electromagnetic fields, we found artificial signals in the nervous system in dependence on WLAN- exposure.

Dynamic adsorption kinetics results indicated that monoethanolamine-carbon dioxide (MEA-CO2) reaction in fixed bed column packed with MEA-impregnated activated carbon (AC) particles is pseudo first order reaction.

Patients with human immunodeficiency virus (HIV), mainly those who live under poor sanitary and socioeconomic conditions, are often diagnosed with Gastrointestinal (GI) tract diseases. The lowest CD4+ T-cell counts are not found in the plasma, but in the GI tract, the biggest HIV source, thus allowing opportunistic infections. Therefore, the aim of the present study was to identify the epidemiological factors of GI infections and the prevalent pathogens in HIV patients from Porto Velho City, Rondônia State.

Infertility is a menace with untoward emotional, financial and sometimes traumatic consequences. This is a retrospective observational study with some interest concerning the epidemiology of tubal infertility in Nigeria. It is the experience of a single center that evaluates the outcome of HSG examination with the main objective of identifying tuberous occlusions at a private Imaging Centre in Makurdi.
