The higher the surface biomass, the more the SAN is absorbed. Under natural conditions, the relative strength of biological nitrogen fixation and plant absorption determine the content of SAN. In the research area, when the depth of groundwater is less than 0.4 m will cause soil salinization, then lead to low species richness; Species richness is exponentially correlated with groundwater depth and decreases with the increase in groundwater depth.This article aimed to estimate the local underground water associations, which will, in turn, be applied to discuss the location of each underground water cluster in the flow system. Additionally, this investigation intended to evaluate underground water's aptness from aquifers of the study area for domestic agricultural activities and the prime sources of alteration in the water chemistry. Geographically, the region does not have the privilege of the river (except the Yamuna in the eastern part) running through it and thus, has to rely heavily on groundwater. Therefore, it is necessary to study the groundwater characteristics in this region. This investigation manifested two sub-surface water associations (groups) showing two prime underground water types in the study area the calcium-magnesium-bicarbonate water-types, groups (clusters) 1 member; and the sodium-bicarbonate-chloride water-types consisting of Group 2 members during post-monsoon and pre-monsoon periods. Group 1 is typical of underground water in recharge regions of the underground water flow system. It is the cleanest underground water type in part except for a few groundwater samples. The highest mean salinity was vested in group 2, the signature of underground waters in discharge regions of the underground water flow system. This investigation observes that three principal elements controlled the hydro-chemistry of underground water in the study area chemical fertilizers from farms, carbonate mineral weathering, calcite, fluorite, silicate minerals, and exchange of cations in the region. All the underground water groups had high sodium (Na) concentrations and will cause the Na-hazard when applied for agricultural activities. Most samples of groups 1 and 2 were within the class II and I area of Doneen's plot during both periods and were therefore acceptable for agricultural activities in the investigation region.QTL mapping studies identified three reliable QTLs of rhizome enlargement in lotus. NnBEL6 located within the confidence interval of the major QTL cqREI-LG2 is a key candidate gene enhancing rhizome enlargement. Lotus (Nelumbo) is perennial aquatic plant with nutritional, pharmacological, and ornamental significance. Rhizome is an underground lotus stem that acts as a storage organ and as a reproductive tissue for asexual production. The enlargement of lotus rhizome is an important adaptive strategy for surviving the cold winter. The aims of this study were to identify quantitative trait loci (QTLs) for rhizome enlargement traits including rhizome enlargement index (REI) and number of enlarged rhizome (NER), and to uncover their associated candidate genes. A high-density genetic linkage map was constructed, consisting of 2935 markers binned from 236,840 SNPs. A total of 14 significant QTLs were detected for REI and NER, which explained 6.7-22.3% of trait variance. Three QTL regions were repeatedly identified in at least 2 years, and a major QTL, designated cqREI-LG2, with a rhizome-enlargement effect and about 20% of the phenotypic contribution was identified across the 3 climatic years. A candidate NnBEL6 gene located within the confidence interval of cqREI-LG2 was considered to be putatively involved in lotus rhizome enlargement. The expression of NnBEL6 was exclusively induced by rhizome swelling. Sequence comparison of NnBEL6 among lotus cultivars revealed a functional Indel site in its promoter that likely initiates the rhizome enlargement process. Transgenic potato assay was used to confirm the role of NnBEL6 in inducing tuberization. The successful identification QTLs and functional validation of NnBEL6 gene reported in this study will enrich our knowledge on the genetic basis of rhizome enlargement in lotus.Heat stress (HS) under well-watered conditions was not detrimental to leaf photosynthesis or yield but modified the elevated CO2 response of photosynthesis and yield in two contrasting wheat cultivars. Climate change is increasing the frequency of extreme events such as heat waves, adversely affecting crop productivity. While positive impacts of elevated carbon dioxide (eCO2) on crop productivity are evident, the interactive effects of eCO2 and environmental stresses are still unclear. To investigate the interactive effects of elevated CO2 and heat stress (HS), we grew two contrasting wheat cultivars, early-maturing Scout and high-tillering Yitpi, under non-limiting water and nutrients at ambient (aCO2, 450 ppm) or elevated (eCO2, 650 ppm) CO2 and 22 °C in the glasshouse. Plants were exposed to two 3-day HS cycles at the vegetative (38.1 °C) and/or flowering (33.5 °C) stage. At aCO2, both wheat cultivars showed similar responses of photosynthesis and mesophyll conductance to temperature and produced similar grain yield. Relative to aCO2, eCO2 enhanced photosynthesis rate and reduced stomatal conductance and maximal carboxylation rate (Vcmax). During HS, high temperature stimulated photosynthesis at eCO2 in both cultivars, while eCO2 stimulated photosynthesis in Scout. Electron transport rate (Jmax) was unaffected by any treatment. eCO2 equally enhanced biomass and grain yield of both cultivars in control, but not HS, plants. HS reduced biomass and yield of Scout at eCO2. Yitpi, the cultivar with higher grain nitrogen, underwent a trade-off between grain yield and nitrogen. In conclusion, eCO2 improved photosynthesis of control and HS wheat, and improved biomass and grain yield of control plants only. Under well-watered conditions, HS was not detrimental to photosynthesis or growth but precluded a yield response to eCO2.

To investigate the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes and identify factors that might affect live births in patients with early-stage endometrial cancer (EEC) and atypical endometrial hyperplasia (AEH).

This retrospective study was performed in a tertiary hospital. Patients (n = 123) with EEC or AEH, who underwent IVF/ICSI treatment between January 2010 and December 2019, were divided into a live birth group and a non-live birth group. Clinical characteristics and IVF/ICSI outcomes were assessed.

A total of 123 patients (28 with EEC and 95 with AEH) underwent 215 ovarian stimulation cycles, resulting in 121 fresh embryo transfer (ET) and 108 frozen-thawed ET. Among 229 ET cycles, 91 (23.7%) of 384 embryos were implanted and 86 pregnancies were achieved, including five ectopic pregnancies (5.8%), 28 miscarriages (32.6%), and 53 live births (61.6%). The clinical pregnancy and live birth rates in each ET cycle were 37.6% and 23.1%, respectively. Fifty-one patients gave birth to 57 live neonates, and the cumulative live birth rate was 41.46%. Multiple logistic regression analysis showed that maternal age, histological type, thin endometrium, and time after complete remission (CR) to IVF cycle started were significantly associated with live births.

The live birth rate after IVF/ICSI is promising in infertile patients with EEC and AEH. A shorter interval between CR and IVF/ICSI treatment might be a positive factor, while age > 35years, endometrial thickness < 8mm on the day of ET, and degree of endometrial lesion progressing into carcinoma cannegatively influence IVF/ICSI outcomes.

 35 years, endometrial thickness  less then  8 mm on the day of ET, and degree of endometrial lesion progressing into carcinoma can negatively influence IVF/ICSI outcomes.

Psychological, emotional, and mental distress affects many patients who experience early pregnancy loss (EPL). A common concern is that the patient's actions or choices caused the loss. Understanding the cause of EPL may improve the distress of EPL patients and their partners. Chromosomal abnormalities leading to a significant portion of EPL. Cell-free DNA (cfDNA) testing, a non-invasive test providing high quality information about the chromosomal makeup of a fetus, may offer assurance that a fetal abnormality caused the loss, and provide more certainty or closure in processing EPL. CfDNA may be a useful adjunct to patient-centered care in the setting of EPL. This commentary explores the possibility of cfDNA testing in lessening the emotional distress that often accompanies EPL.

The peer reviewed literature was explored for manuscripts addressing (1) the potential for cfDNA serum testing for patients experiencing EPL and screening products of conception to determine the cause of EPL; and/or (2) the impacucing feelings of guilt and providing closure to those who learn the loss was associated with chromosomal abnormality. Further trials and studies that explore the intersection of mental health of EPL on patients should explore the efficacy of cfDNA testing as an adjunct to patient-centered care in these cases.Radiation therapy is a well-established, minimally invasive method of treating brain tumors. In recent years, the number of post-radiotherapy patients has increased, and delayed side effects are evident. De novo aneurysm formation after radiation often manifests as fatal subarachnoid hemorrhage (SAH), resulting in severe clinical outcomes. Nevertheless, the prognosis and therapeutic efficacy of radiation-induced aneurysms (RIAs) remain unclear. Using the PubMed database from 1980 to 2021, we screened 45 articles (53 individual cases) on RIAs; approximately 70% of RIAs were diagnosed after rupture. Of 38 ruptured RIAs, 12 (31.6%) had modified Rankin scale (mRS) 5-6. On the other hand, all unruptured RIAs (15 cases) recovered without neurological deficits (p = 0.012). Ten of the 39 ruptured RIAs were treated surgically, and 22 were treated endovascularly. There was no significant difference in mRS between treatment modalities (p = 0.393), but conservative therapy was significantly related to unfavorable outcomes (p = 0.025). To improve clinical outcomes, RIAs need to be diagnosed before rupture. Surgeons should be aware of de novo aneurysm formation in patients long after radiation therapy.

Heterotopic pancreas (HP) refers to the presence of abnormally located pancreatic tissue without any anatomic or vascular continuity with the main body of the pancreas. learn more HP can occur in the gastrointestinal tract and be complicated by gastrointestinal bleeding, pancreatitis, obstruction, or malignant generation. Specifically, perforation of the gastrointestinal tract because of HP is extremely rare.

A 91-year-old woman was diagnosed with duodenal perforation, and an emergency laparoscopic operation was performed. The operative findings indicated a tumor and duodenal wall perforation. The tumor and the perforated site were resected with a linear stapler. Histopathological examination revealed the presence of HP tissue in the submucosal layer around the diverticulum without any signs of inflammation. The perforated site was not covered by HP tissues, and the duodenal wall might have been weaker than the other areas, which could have caused the internal pressure to increase and led to the perforation.

Preoperative HP diagnosis is difficult, and it is crucial to consider HP as the differential diagnosis in gastrointestinal perforations.
