Abstract Based on the characteristics of Kummell’s disease (KD) and related anatomical structures of the thoracolumbar spine, a novel bone cement screw system has been designed to effectively avoid the cement loosening and displacement. This experiment aimed to assess the biological effects of the novel bone cement screw system in KD on fresh cadaveric thoracolumbar spine specimens, thereby discussing its potential application value and providing a foundation for clinical implementation. This study employed a total of 50 fresh female adult cadaver specimens. Each specimen underwent extraction

Background: Cytochrome P450 2E1 (CYP2E1) is a main enzyme which plays a major role in activating and detoxifying many xenobiotics, carcinogens and drugs. Available studies suggest that CYP2E1 single nucleotide polymorphisms (SNPs) are involved in the risk of developing certain cancers after exposure to carcinogens. The purpose of the present study was to assess genotype and allele frequencies of polymorphic CYP2E1*5B in the Iranian population. Material and Methods: This study was performed on 200 healthy individuals (female: 100, male: 100) in medical laboratories of Ahvaz during 2011. The CYP

The objective of this work was to investigate the influence of housing conditions, number of farrowing and number of pigs in litter on weight loss in sows during lactation. The experiment included 60 sows, half breed developed by cross breeding of Big Yorkshire and Swedish Landrace in lactation. Body weight of the sows (kg) was determined 2nd, 7th, 14th, 21st and 28th day after farrowing. On the basis of the obtained values, there was calculated the difference in body weight between two consecutive investigation periods. The sows were divided into two groups and held in different housing condi

Abstract Background Mild cognitive impairment in Parkinson’s disease (PD-MCI) is associated with an increased risk of cognitive decline. PD-MCI is characterized by impairments in executive function and visuospatial recognition. The visuospatial n-back test is useful for assessing both domains. The 0-back test reflects visuospatial recognition, while the 1-back and 2-back tests reflect working memory. Cholinesterase inhibitors are effective in the treatment of PD-MCI and dementia in PD (PDD). Although some studies have reported the efficacy of memantine for PDD, the therapeutic efficacy of mema

Mechanical ventilation is a primary therapy for patients with respiratory failure. However, incorrect ventilator settings can cause lung damage. Optimising ventilation while minimising risk is complex in practice. A common lung protective strategy is to titrate positive end-expiratory pressure (PEEP) to the point of minimum elastance. This process can result in additional available lung volume due to alveolar recruitment but comes with the risk of subjecting the lungs to excessive pressure and lung damage. Predictive elastance models can mitigate this risk by estimating airway pressure at a hi

Gene editing in large animals like buffalo is challenged by mosaicism, where cells contain both wild-type and mutant alleles, complicating the creation of genetically modified F0 animals in a single step. Traditionally, electroporation is performed on zygotes post in vitro fertilization (IVF), but mature oocytes’ higher permeability suggests earlier intervention might reduce mosaicism and enhance editing efficiency. We hypothesized that the timing of electroporation before in vitro fertilization (IVF) can increase the rates of biallelic mutation for multiple gene knockout as the permeability o

Potato is an important food crop with high water-use-efficiency but low drought tolerance. The bottleneck in drought tolerance breeding is phenotyping in managed field environments. Fundamental research on drought tolerance is predominantly done in container-based test systems in controlled environments. However, the portability of results from these systems to performance under field conditions is debated. Thus, we analyzed the effects of climate conditions, container size, starting material, and substrate on yield and drought tolerance assessment of potato genotypes compared to field trials.
