The state of Haryana in northeastern India has an excellent sub-tropical climate for the development of fresh water fish culture in a variety of aquatic bodies. Aquaculture not only plays an important role in nutrition but also in the rural economy of the State. The main purpose of the present study was to identify the primary production and fish production patterns in village ponds under different management practices. With a more or less narrow range of primary production, varying fish production and growth rates were recorded, indicating the influence of a combination of environmental and management factors. There was no close relation between primary production and fish production in the rural fish ponds of Haryana, India. Sudden and considerable fluctuations in dissolved oxygen concentration and pH impair the proper functioning of other trophic communities, supported the dominance of decomposition processes, i.e., anaerobiosis, and lead to further degradation and loss of the control functions of the whole water ecosystem. Increased organic load can be considered as a general signal of reaching the instability of aquatic ecosystem and decrease of production efficiency The optimum conditions for increased fish productivity were found to be the adequate DO level (>4 mg L -1 ) and appropriate pH (6 < pH < 9), low BOD (<1.6 mg L ).

BackgroundBombax ceiba is used traditionally to treat bone disorders, rheumatism, and joint pain. The aim of the study is to carry out osteogenic activity in-vitro and anti-osteoporotic activity in-vivo of stem bark of B. ceiba in surgical ovariectomy model in female rats.MethodsPlant drug: B. ceiba stem bark was extracted with solvents petroleum ether and methanol using Soxhlet extraction. In-vitro osteoblastic proliferation study was performed using UMR-106 cell lines. Both the extracts were undergone to acute toxicity study as per OECD423 guidelines. Female Wistar albino rats 180-240 g were used (n = 6). Surgical ovariectomy was performed under anesthesia to induce bone porosity and loss in all animals except normal control and sham control. Each extract was administered at two dose level: 100 and 200 mg/kg and the standard Raloxifene was given at 1 mg/kg orally for 28 days. The phytochemical study of both the extracts was performed using HPLC and HPTLC.ResultsA significant osteoblast cell proliferation and alkaline phosphatase activity were observed with B. ceiba extracts in UMR-106 cell lines. Surgical removal of ovaries produced significant (p < 0.05) decline in bone mineral density, bone breaking strength, serum ALP, calcium, phosphorus, and estradiol level and marked bone tissue destruction in histology. Administration of petroleum ether and methanolic extract for 28 days significantly (p < 0.05) ameliorated the consequences of ovariectomy induced bone porosity and restored the normal architecture of bone, as compared to OVX control. The phytochemical screening of both the extracts were also carried out. The quantification of phytoconstituents showed the presence of β-sitosterol and lupeol in petroleum ether extract, whereas the lupeol is also quantified in the methanolic extract. The presence of gallic acid was quantified in methanolic extract using HPLC.ConclusionB. ceiba: stem bark ameliorated the state of bone fragility and fracture possibly due to estrogenic modulation, as also confirmed by in-vitro osteogenic activity which may be due to the presence of lupeol, gallic acid and β-sitosterol constituents of the plant.

Yolk sac tumor (YST) is a rare neoplasm that affects children and adolescents. Fine needle aspiration biopsy is an extremely useful procedure for the diagnosis of YST. Main objective is to describe the characteristic cytological features of fine needle aspirates of YST. We report a case of YST in a 4-year-old male child occurring at paravertebral region showing cytomorphological details.

Manned-Unmanned Teaming (MUM-T) can be defined as the teaming of aerial robots (artificial agents) along with a human pilot (natural agent), in which the human agent is not an authoritative controller but rather a cooperative team player. To our knowledge, no study has yet evaluated the impact of MUM-T scenarios on operators' mental workload (MW) using a neuroergonomic approach (i.e., using physiological measures), nor provided a MW estimation through classification applied on those measures. Moreover, the impact of the non-stationarity of the physiological signal is seldom taken into account in classification pipelines, particularly regarding the validation design. Therefore this study was designed with two goals: (i) to characterize and estimate MW in a MUM-T setting based on physiological signals; (ii) to assess the impact of the validation procedure on classification accuracy. In this context, a search and rescue (S&amp;R) scenario was developed in which 14 participants played the role of a pilot cooperating with three UAVs (Unmanned Aerial Vehicles). Missions were designed to induce high and low MW levels, which were evaluated using self-reported, behavioral and physiological measures (i.e., cerebral, cardiac, and oculomotor features). Supervised classification pipelines based on various combinations of these physiological features were benchmarked, and two validation procedures were compared (i.e., a traditional one that does not take time into account vs. an ecological one that does). The main results are: (i) a significant impact of MW on all measures, (ii) a higher intra-subject classification accuracy (75%) reached using ECG features alone or in combination with EEG and ET ones with the Adaboost, Linear Discriminant Analysis or the Support Vector Machine classifiers. However this was only true with the traditional validation. There was a significant drop in classification accuracy using the ecological one. Interestingly, inter-subject classification with ecological validation (59.8%) surpassed both intra-subject with ecological and inter-subject with traditional validation. These results highlight the need for further developments to perform MW monitoring in such operational contexts.
