purpose: to compare corneal endothelial cell features after cataract surgery performed using fixed torsional or conventional (pulse) ultrasound mode. methods: in this randomized comparative study, 60 eyes were randomly and equally divided into two groups of torsional or longitudinal mode phacoemulsification. all surgeries were performed by an experienced surgeon, and the outcomes were evaluated...

The brain has an impressive ability to withstand neural damage. Diseases that kill neurons can go unnoticed for years, and incomplete brain lesions or silencing of neurons often fail to produce any behavioral effect. How does the brain compensate for such damage, and what are the limits of this compensation? We propose that neural circuits instantly compensate for neuron loss, thereby preservin...

purpose: to assess the short-term effect of mitomycin-c (mmc) 0.02% on endothelial cell density and morphology after photorefractive keratectomy (prk) in patients with moderate myopia. methods: forty-two eyes of 21 participants with moderate myopia (range, -4.0 to -8.0 d) underwent prk with mmc 0.02% for 40 seconds. specular microscopy was performed preoperatively and repeated 6 months after su...

Plant lateral aerial organ (LAO) growth is determined by the number and size of cells comprising the organ. Genetic alteration of one parameter is often accompanied by changes in the other, such that the overall effect on final LAO size is minimized, suggested to be caused by an active organ level 'compensation mechanism'. For example, the aintegumenta (ant) mutant exhibits reduced cell number ...

Background. Athletes’ performance in sporting events is influenced by several factors. One of them is how fair the compensation system is implemented. The proper compensation will motivate the athlete to perform better. Otherwise, it will be a loss for the team. Objectives. The purpose of this study was to determine the effect of compensation on the sports achievements of South Sulawesi athlet...

Third-party punishment and third-party compensation are primary responses to observed norms violations. Previous studies mostly investigated these behaviors in gain rather than loss context, and few study made direct comparison between these two behaviors. We conducted three experiments to investigate third-party punishment and third-party compensation in the gain and loss context. Participants...

Chromosomal or segmental aneuploidy-the gain or loss of whole or partial chromosomes-is typically deleterious for organisms, a hallmark of cancers, and only occasionally adaptive. To understand the cellular and organismal consequences of aneuploidy, it is important to determine how altered gene doses impact gene expression. Previous studies show that, for some Drosophila cell lines but not othe...

the most important obligation of the carrier of the goods is to deliver it safe, perfect and well timed to the destination. obviously the loss, missing and delay of the deliver of goods to the destination leads to carrier’s liability. in this paper we examine the calculating method of compensation and its maximum and its exceptions in international contracts that involved of cmr convention. cri...
