Mesonephric-like adenocarcinoma of the ovary with co-existent endometriosis: A case report and review of the literature

© 2020 The Authors Introduction: Mesonephric-like adenocarcinoma (MLA) is a rare malignant gynecologic neoplasm occurring in the uterine corpus and ovary. The morphological and immunohistochemical characteristics of MLA closely resemble that of cervical mesonephric adenocarcinomas, but whether they share a common histogenesis remains unclear. Two main theories for histogenesis of MLAs include the origination of these neoplasms from mesonephric remnants, as is the case for cervical mesonephric adenocarcinoma, versus the differentiation along a mesonephric pathway from Mullerian lesions. Case: A 67-year-old presented after a right salpingo-oophorectomy for a complex ovarian mass revealed a mesonephric-like adenocarcinoma of the ovary and endometriosis. She underwent a total abdominal hysterectomy, pelvic lymphadenectomy, and infra-colic omentectomy, and diagnosed with Stage IA mesonephric-like adenocarcinoma of the ovary. At 18 months post-operatively, the patient developed flank and abdominal pain and was found to have multiple sites of recurrent disease. She was referred to medical oncology for chemotherapy as she was not a candidate for surgical cytoreduction. Discussion: This case demonstrates the aggressive nature of ovarian MLA and the need for a multidisciplinary approach when determining the treatment. In addition, this case provides further evidence to support the theory that at least a subset of MLAs arises from a Mullerian lesion which then differentiates down a mesonephric pathway

Mapping Epileptic Networks Using Simultaneous Intracranial EEG-fMRI

Background: Potentially curative epilepsy surgery can be offered if a single, discrete epileptogenic zone (EZ) can be identified. For individuals in whom there is no clear concordance between clinical localization, scalp EEG, and imaging data, intracranial EEG (icEEG) may be needed to confirm a predefined hypothesis regarding irritative zone (IZ), seizure onset zone (SOZ), and EZ prior to surgery. However, icEEG has limited spatial sampling and may fail to reveal the full extent of epileptogenic network if predefined hypothesis is not correct. Simultaneous icEEG-fMRI has been safely acquired in humans and allows exploration of neuronal activity at the whole-brain level related to interictal epileptiform discharges (IED) captured intracranially. Methods: We report icEEG-fMRI in eight patients with refractory focal epilepsy who had resective surgery and good postsurgical outcome. Surgical resection volume in seizure-free patients post-surgically reflects confirmed identification of the EZ. IEDs on icEEG were classified according to their topographic distribution and localization (Focal, Regional, Widespread, and Non-contiguous). We also divided IEDs by their location within the surgical resection volume [primary IZ (IZ1) IED] or outside [secondary IZ (IZ2) IED]. The distribution of fMRI blood oxygen level-dependent (BOLD) changes associated with individual IED classes were assessed over the whole brain using a general linear model. The concordance of resulting BOLD map was evaluated by comparing localization of BOLD clusters with surgical resection volume. Additionally, we compared the concordance of BOLD maps and presence of BOLD clusters in remote brain areas: precuneus, cuneus, cingulate, medial frontal, and thalamus for different IED classes. Results: A total of 38 different topographic IED classes were identified across the 8 patients: Focal (22) and non-focal (16, Regional = 9, Widespread = 2, Non-contiguous = 5). Twenty-nine IEDs originated from IZ1 and 9 from IZ2. All IED classes were associated with BOLD changes. BOLD maps were concordant with the surgical resection volume for 27/38 (71%) IED classes, showing statistical global maximum BOLD cluster or another cluster in the surgical resection volume. The concordance of BOLD maps with surgical resection volume was greater (p < 0.05) for non-focal (87.5%, 14/16) as compared to Focal (59%, 13/22) IED classes. Additionally, BOLD clusters in remote cortical and deep brain areas were present in 84% (32/38) of BOLD maps, more commonly (15/16; 93%) for non-focal IED-related BOLD maps. Conclusions: Simultaneous icEEG-fMRI can reveal BOLD changes at the whole-brain level for a wide range of IEDs on icEEG. BOLD clusters within surgical resection volume and remote brain areas were more commonly seen for non-focal IED classes, suggesting that a wider hemodynamic network is at play

Milk Production and Nutrient Efficiency of Lactation Goats on Diet Containing Linseed Cake, Mustard Cake and Guar Korma with Urea in Concentrates

Protein supplements, those conventionally used in goat feeding includes oil meals of ground nut, soybean meal, linseed and til etc., which are very costly and their availability is limited for ruminant feeding as these are most used in pig and poultry rations. However, mustard (Brassica juncea) oil meal is available in plenty at cheaper prices but their utilization in goat feeding is limited due to its bitterness (Pailan and Singhal, 2007), which arises upon degradation of glucosinolate contents of mustard (Tripathi and Mishra, 2007). Ruminant animals have unique capability of bioconversion of nonprotein nitrogen substances into microbial protein, which can also substitute organic protein supplement. Guar korma is another high protein feed resource available at cheaper prices, which can also be used in animal feeding in limited quantities. The use of mustard cake in replacement of linseed cake upto 75% in concentrates of lactating Jamunapari goats have been demonstrated earlier. However, information of guar korma use in goat feeding is in scanty. The level and quality of dietary protein and fat have influence on milk production and quality (Tripathi, 2014) Therefore, present experiment aimed to utilized mustard oil meal, urea and guar korma in replacement of conventional linseed oil cake as protein supplement in concentrate mixture of lactating goats feeding and assess the nutrient utilization efficiency for milk production

Circulating myostatin is reduced with aging in humans but not altered by short-term, high intensity training

Introduction: Ageing involves a loss of muscle mass and function. The rate of decline is associated with negative health outcomes and increased mortality (1). Muscle atrophy is observed at a predictable rate from 30 years of age (2), however maintenance of function is seen in masters athletes > 60 years of age (3). Myostatin acts as a negative regulator of muscle mass (4) and underlies hypertrophy with chronic resistance training (5) and atrophy in chronic conditions (4). Experiment 1: Declared healthy participants (n = 83, 18 - 75 years of age, 36 male, 47 female) were recruited. Body composition, metabolic rate, grip strength and 6-minute walk test were recorded. Venous blood was collected and total myostatin concentration (herein referred to as myostatin) quantified by enzyme-linked immunosorbent assay. Total myostatin was lower in females compared with males (2176.1 [135.3] vs. 2788.7 [180.2] pg.mL-1 [p = 0.007]). Stepwise regression observed that myostatin concentration is best predicted firstly by gender, then by age (r = 0.399, p = 0.02), and was not further improved by the addition of measures of metabolism, muscle mass or function. Experimental 2: A cohort of aged sedentary (SED) males (n = 14; 63.9 [5.6] years of age) and masters athletes (lifelong exerciser [LEX]; n = 10, 61.1 [5.8] years of age) completed 6 weeks of high intensity interview training (HITT). Two way ANOVA suggested no group (SED, LEX) × time (pre, post) interaction on myostatin concentration (p = 0.649), nor a main effect of time (p = 0.757), however there was a trend towards increased myostatin in the LEX group relative to SED (p = 0.083). Discussion: Loss of muscle mass and function occurs at a predictable rate from ~30 years of age, however the rate of loss differs between active and inactive populations. Here we demonstrate that total circulating myostatin decreases as age increases, and differs significantly between males and females. Total circulating myostatin negatively correlates with increasing age, however alterations in myostatin do not appear after short term training interventions. Longer term activity may alter myostatin, thus our next work will follow up experiment 2 with a 3 year longitudinal analysis

Effect of phyto additives and Saccharomyces cerevisiae on rumen ferementation and microbial profile in buffaloes

To study the effect of plants containing plant secondary metabolites (PSM) and Saccharomyces cerevisiae on rumen ferementation and microbial profile, four fistulated adult buffaloes were fed in 4×4 Latin square design. The four groups were, control, without additive; T1, mixture of harad seed pulp and garlic bulb (2% of DMI); T2, S. cerevisiae (350g feremented feed containing S. cerevisiae 106 /g); T3, mixture of harad seed pulp, garlic bulb and S. cerevisiae. All the animals were fed on a basal diet consisting of wheat straw and concentrate mixture in 50:50 ratio. Daily DM intake was similar in all the four groups. Feeding of any of the dietary treatments did not affect rumen fluid pH, concentration of ammonia N and lactic acid. The total volatile fatty acids and its fractions except butyrate were also not influenced by supplementation of any of the additives. The activities of ruminal enzymes viz. carboxymethylcellulase, xylanase, avicelase and acetyl esterase were similar in all the four groups. The rumen microbial density of total bacteria, Ruminococcus flavefaciences, R. albus, methanogens and fungi were not changed whereas Fibrobacter succinogenes and protozoa populations were significantly reduced in T1 but were at par of control by inclusion of yeast in the diet. It is concluded that mixture of harad and garlic alone or in combination with yeast culture did not influence rumen fermentation however microbial profile (F. succinogenes and protozoa) was improved by feeding yeast as additive. The additives tested seem to have potential to alter rumen microbial ecology and can further be explored for its efficacy in improving the performance of the animals

Cenomanian-Turonian sea-level transgression and OAE2 deposition in the Western Narmada Basin, India

We report the Narmada Seaway began in India during the largest global sea-level transgression and Oceanic Anoxic Event 2 (OAE2) δ¹³C excursion during the late Cenomanian to early Turonian. The transgression progressed eastward during the Turonian-Coniacian and reached Jhilmili by the end of the Maastrichtian. During this time the Narmada and Godavari Seaways may have joined via the Narmada-Tapti rift and formed a Trans-India Seaway. The history of this major seaway is entombed in a fossil-rich marine transgression of the tectonically active Narmada rift zone. We examined this transgression in the western Narmada Basin, Gujarat, to improve age control based on planktic foraminifera and ostracods and evaluate paleoenvironmental changes based on the Cenomanian-Turonian OAE2 δ¹³C excursion, δ¹⁸O records, and mercury concentrations in sediments as index for volcanic eruptions. Results reveal the onset of the OAE2 δ¹³C excursion began in the western Narmada Basin during the late Cenomanian coeval with the sea-level transgression and first influx of planktic and benthic foraminifera in the Nimar Sandstone that overlies Archean rocks. The OAE2 δ¹³C excursion peak was recorded in oyster biostromes followed by fluctuating values of the δ¹³C plateau in the overlying Limestone with oysters beds, and gradual decrease to background values by the early Turonian. We tested the age of the transgression and δ¹³C excursion based on planktic foraminifera and ostracod biostratigraphy and successfully compared the results with the Pueblo, Colorado, Global Section and Stratotype Point (GSSP), and the eastern Sinai Wadi El Ghaib section of Egypt

A Study on Mortality Profile among Fifty Plus-(50+-) Population (FPP) of India: A 5-Year Retrospective Study at New Delhi District

Objectives. To find out the mortality profile vis-a-vis different epidemiological factors at the time of autopsy among the 50+-Population. Material and Method. A five-year retrospective evaluation of medicolegal records between 2006 and 2010 was done at Lady Hardinge Medical College, New Delhi. Results. A total of 493 (17.78%) cases belonged to 50+-Population age group out of total 2773 autopsies performed. The proportion of unidentified/unknown persons among this age group was 36.51%. The unnatural and natural causes constituted 44.62% and 55.38% cases, respectively. The unspecified pneumonitis (50.18%) was reported as the commonest cause followed by coronary artery disease and respiratory tuberculosis among natural ones and the transport accident (57.27%) followed by accidental and intentional self-poisoning and exposure to noxious substances and falls among the unnatural ones. Conclusion. The findings reveal that this age group most commonly dies of natural causes rather than the unnatural ones even in autopsy cases. They have definite cure with timely interventions. The study also points out the need to devise the road and home safety measures to reduce mortality among the study population
