conclusions in squatting position the number of spinal needle-bone contacts was lower compared to the traditional sitting position, nonetheless ease of needle insertion or space identification was the same in the both groups. results the total number of spinal needle bone contact was statistically lower in the squatting position compared to traditional sitting position group (222 versus 230 res...

conclusion our findings support prone positioning for premature infants. therefore, it is advisable to nicu staff that if there is no obstacle for changing the infant’s position, prone position in infants with respiratory complications during receiving n-cpap in nicu can be useful. regarding the fact that prone position is a risk factor for sudden infant death syndrome , prone position should b...

BACKGROUND The natural history and carcinogenicity of rare and novel HPV types is unclear. MATERIALS AND METHODS From a total of 5,964 women tested for HPV by PCR and sequence analysis, Pap smears from 293 patients harbouring mono-infection with low-risk, undetermined-risk or novel HPV genotypes were investigated. RESULTS Sixty-three percent of patients had ASC-US, 23% LSIL, 9% were negativ...

The distribution of local preferred directions and motion sensitivities within the receptive fields of so-called tangential neurons in the fly visual system was previously found to match optic flow fields as induced by certain self-motions. The complex receptive-field organization of the tangential neurons and the recent evidence showing that the orderly development of the fly's peripheral visu...

BACKGROUND Cutaneous leishmaniasis (CL) is a neglected worldwide, zoonotic, vector-borne, tropical disease that is a threat to public health. This threat may spread from endemic to non-endemic areas. Current research has exploited epidemiological, molecular and phylogenetical studies to determine the danger of an outbreak of CL in the borderline area between northern and central Iraq from 2014-...

background: proper sleep is essential for the development of premature infants. infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. to compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. this study is a randomized clinical trial which was conducted in neonatal ...

This study addresses a meta-analysis of the distribution Rickettsia spp. in Neotropical region, as well their associations with ticks and vertebrates. A total 219 published reports on target region were compiled, providing 599 records 31 species recorded 50 Ixodidae. The aim is to capture phylogenetic relationships between rickettsiae carrying them focus co-speciation ticks-rickettsiae. We comp...

Anaerobic digestion is an effective biotechnological process for treatment of different agricultural, municipal and industrial wastes. However, it is a very unstable process in regard to the biogas reactors operation. This is due to the complicated interactions between different microbial species as well as of the complex transformations of the organic matter affected by a variety of environmen...

The intricate geological evolution of the Arctic Ocean is paralleled by complexities in the biogeographical and phylogenetical histories of the Arctic biota, including bryozoans. Here we present revised taxonomic descriptions for all known species of the bryozoan genus Pseudoflustra, and use the present-day distributions and phylogenetic relationships between these species to infer the historic...
