Pattern of Morphological Anomalies of Uterus as Observed by Modern Investigation Techniques

Background: Due to the high prevalence and possible impact on the reproductive health of the of woman, congenital uterine malformation of female genital tract is a challenge for the therapeutic decision-making process. The current study aimed to evaluate the morphological anomalies of the uterus as observed by modern investigation techniques. Methods: This cross-sectional observational study was done in Prathima Institute of Medical Sciences, Nagnoor, Karimnagar, Telangana state. Women who were infertile and anxious to conceive and women were subjected to 2D ultrasound Screening followed by Hysterosalpingography. Those women who were fertile and found to have uterine anomalies and needed reconfirmation of the provisional diagnosis were subjected to Hysterosalpingography. Results: Out of n=300 cases studied n=288 (96%) were with normal uterine anatomy and n=12 (4%) cases were detected with uterine malformations as seen by USG. N=5 (40.5%) had a Bicornuate Uterus. While uterus didelphys and unicornuate uterus were seen in n=2 (16.67%) each. Arcuate uterus, uterine septum, uterine Aplasia/Hypoplasia were seen in n=1(8.33%) women each respectively. Conclusion: Due to the psychological consequences associated with infertility, the effects of uterine anomalies on the life of women are very important. It is critical to know the exact nature of the anomaly, to plan for the most appropriate treatment modality. As most of these anomalies cannot be rectified by medical management, they need surgical correction. For optimal results, it is important to know the exact type of anomaly for surgical correction. The 2D USG can be recommended as the basic modality to evaluate uterine anomalies. HSG/MRI may be used to delineate detail of anomalies if initially detected by the 2D scan.

Traditional Selection Potato Varieties and Their Resistance to the 28-punctata Potato Ladybug Henosepilachna vigintioctomaculata (Coleoptera: Coccinellidae) in the Southern Russian Far East

Background: Henosepilachna vigintioctomaculata is a polytrophic pest, causing the greatest damage to plants from the nightshade family. The study aimed to research the resistance of potato cultivars that are promising for breeding to damage by a potato ladybug in laboratory and field experiments. Methods: In laboratory experiments, the indicators of fertility, mortality and duration of development, morphological anomalies and the effect of potato varieties on the composition of Epilakhna’s hemolymph were studied. The sample consisted of 50 individuals with a slight predominance of females. The experiment used 13 varieties of potatoes. Result: A specific dependence of the frequency of phytophage anomalies on the variety was revealed. The influence of nutrition on survival and the timing of ontogenesis has been established. The results obtained indicate the high breeding value of the material when recommending it for cultivation in regions with a high number of pests, as well as when creating new varieties.

Left double polar renal arteries, left triplicate (preaortic, accessory and retroaortic) renal veins associated with extrinsic pelviureteric junction obstruction and posterior nutcracker phenomenon

The renal vasculature and its various congenital anomalies have been studied and documented widely in the literature. However, the concomitant occurrence of renovascular morphological anomalies with vascular compression phenomena in a single patient is a rarity. This is a case of a patient with double left renal arteries, preaortic, accessory and retroaortic left renal veins. There was also associated with vascular compression phenomena in the form of posterior nutcracker phenomenon and pelviureteric junction obstruction (PUJ) due to the double-crossing inferior left polar renal artery and retroaortic vein.

Identification of Novel Mutation Sites in DNAH1 of Multiple Morphological Anomalies of the Flagella Patients

BackgroundMultiple morphological anomalies of the sperm flagella (MMAF) is a term used to describe abnormalities in sperm morphology, which lead to primary infertility in males. Intracytoplasmic sperm injection (ICSI) is an effective treatment for MMAF. However, ICSI failure rates remain high in MMAF patients. Our purpose was to investigate novel gene mutations in a cohort of nineteen patients with MMAF and assess the impact of these mutations on assisted reproductive therapy.MethodsWe recruited nineteen infertile patients with MMAF and twenty healthy men with proven fertility at the Affiliated Yantai Yuhuangding Hospital of Qingdao University. The morphology of the spermatozoa was observed using Papanicolaou staining and the ultrastructure of the spermatozoa was inspected using transmission electron microscopy. Gene mutations were evaluated using whole-exome sequencing and novel mutations were further validated in patients and their parents using Sanger sequencing. The effect of these novel mutation sites on the expression of DNAH1 was analysed using immunofluorescence, and the effect of these novel mutations on pregnancy outcome was analysed using intracytoplasmic sperm injection (ICSI). ResultsSpermatozoa from 19 patients presented with a typical MMAF phenotype including severe ultrastructural defects. We identified ten novel mutation sites in the DNAH1 locus from six of these patients, none of which were identified in DNAH1 or the other MMAF-related genes from the twenty men with proven fertility. In the sperm from these patients, DNAH1 was absent. Three patients with DNAH1 mutation who underwent intracytoplasmic sperm injection (ICSI) had a good outcome. ConclusionHere, we describe several novel compound heterozygous mutations and a novel homozygous mutation in DNAH1 from six independent MMAF patients. This study adds to the body of knowledge surrounding the genetic landscape of MMAF and DNAH1 improving our ability to diagnose and treat MMAF efficiently.

Planktonic Invertebrates in the Assessment of Long-Term Change in Water Quality of the Sorbulak Wastewater Disposal System (Kazakhstan)

The multicomponent composition of wastewater makes it challenging to assess its quality objectively, but the last one is a prerequisite for the safe re-use of wastewater. The solution to this problem should be aimed at finding criteria that make it possible to increase the objectivity of assessing the water quality of reservoirs with multicomponent pollution. This work analyzes the water quality of the Sorbulak wastewater disposal system in the summer of 2017, based on chemical variables and zooplankton structure and assess the long-term changes in the water quality of Sorbulak. According to the Kruskal–Wallis test, in 2017, the differences between the studied water bodies in the content of nutrients and heavy metals were mostly insignificant. From 2000–2002 to 2017, nitrate, nitrite nitrogen, and heavy metals in Sorbulak significantly decreased. Zooplankton communities consisted of a relatively small number of eurybiontic species resistant to environmental factors. The variability of the quantitative variables of zooplankton was associated with the nutrients. Males dominated the population of the cyclopoid copepods Acanthocyclops trajani. In 2000–2002 individuals with morphological anomalies were found in cyclopoid copepods populations, but were absent in 2017. The appearance of individuals with morphological anomalies was associated with copper or lead. The chemical data and structure of zooplankton communities indicated that the toxic pollution of Sorbulak decreased by 2017 compared to 2000–2002. Our results demonstrate that the structural variables of zooplankton communities could be successfully used to assess the water quality of water bodies with mixed pollution. We recommend using not only the traditional set of biological variables (abundance, biomass, diversity indices, and the average mass of an individual), but also data on the structure of species dominance, the sex structure of copepod populations, and the presence of individuals with morphological anomalies for monitoring of water bodies with mixed pollution.
