| 1 | Evaluation of trend in semen analysis for 11 years in subjects attending a fertility clinic in India显示文摘Aim: The data on semen analysis of subjects attending the Fertility Clinic at NIHFW (National Institute of Health and Family Welfare) Munirka, New Delhi for the last 11 years were analyzed to verify the claims and speculations on declining sperm counts in men. Methods: Approximately 10 % of the records every year starting from 1990 to 2000 (numbering 1176 in total) were randomly selected for analysis. Subjects with azoospermia or severe oligozoospermia were excluded from analysis. Results: The average age of the men attending the infertility clinic was 31.2 years. The average semen volume and sperm count were found to be (2.6 ± 0.1) mL and (60.6 ±0.9)× 10^6/ml., respectively. No significant decline in sperm counts was observed in anyyear during the entire studyperiod. Only 1.8 % of the total number of sperm counts in the random sampling were less then 20×10^6/mL. On the basis of WHO criteria on motility, the total percentage of non-progressive and non-motile sperm in the ejaculate was higher (63 %) as compared to the combined categories of slow and rapid linear progressive. Conclusion: The present study has confmned similar findings from other different countries that declining sperm counts in humans is not a global phenomenon.

| 2 | Screening Azadirachta indica tree for enhancing azadirachtin and oil contents in dry areas of Gujarat,India显示文摘Azadirachta indica seed samples were collected from four different agro-ecological regions(AERs) viz.,AER-2,AER-4,AER-5A and AER-5B of Gujarat state,India during 2000 to 2002 with an aim to assess variability in azadirachtin,oil and fatty acids content of the seeds and assess correlation of these parameters with morphological characters.Azadirachtin,oil and fatty acids content indicated significant(p<0.01) variations between years and AERs in Gujarat.The azadirachtin ranged from 142 to 9 527 μg·g-1 seed kernel with an average of 2 426 μg·g-1 for the state.AER-5B recorded highest azadirachtin and oil content.Fatty acid composition was found to be affected by environmental factors particularly varying degree of annual rainfall and temperature during fruit ripening period.Conclusively trees growing in AER-5B performed better in term of azadirachtin,oil and stearic acid content.Tree girth at breast height showed no significant relation with these biochemicals. | U.K.Tomar G.Singh N.Kaushik | 2011 | Journal of Forestry Research2011,22,2: | 4 |
| 3 | Application of seminal germ cell morphology and semen biochemistry in the diagnosis and management of azoospermic subjects显示文摘To evaluate whether the study of seminal germ cell morphology (SGCM) and semen biochemistry could be fruitfully utilized for the diagnosis and management of azoospermic subjects. Methods: In the semen, mature and immature germ cells are contributed by the testes, 70% of glycerylphosphoryl choline (GPC) by the epididymis, fructose mostly or solely by the seminal vesicles and acid phosphate (ACP) by the prostate. In 16 normal volunteers, 12vasectomized subjects and 186 azoospermic subjects, these parameters have been studied and the data have been analyzed. Results: Both mature and immature germ cells are absent in the semen of vasectomized subjects as well as in obstructive azoospermia; GPC level is also significantly decreased in both these groups. In cases with non-obstructive azoospermia immature germ cells are present and seminal GPC, ACP and fructose levels are normal. The diagnosis of obstructive and non-obstructive azoospermia based on these parameters correlated well with 'correct' testicular biopsy findings. In some cases of azoospermia due to hypospermatogenesis or spermatogenic developmental arrest, the SGCM studies were very helpful in objectively monitoring the response of the germinal tissue to specific treatments. Conclusion: SGCM and semen biochemical parameters are very valuable non-invasive markers for differentiating obstructive from non-obstructive azoospermia. The SGCM findings serve as a dependable non-invasive testicular marker with high predictive value. | Somnath Roy A.Banerjee H.C.Pandey G.Singh G.L.Kumari | 2001 | Asian Journal of Andrology2001,3,1: | 4 |

| 9 | Performance analysis of cognitive radio networks using channel-prediction-probabilities and improved frame structure显示文摘This paper focuses on potential issues related to the random selection of a sensing channel that occurs after the prediction phase in a Cognitive Radio Network (CRN).A novel approach (Approach-l)for improved selection is proposed,which relies on the probabilities of channels by which they are predicted idle.Further,closed-form expressions are derived for the throughput of Cognitive Users (CUs)in the conventional and proposed approaches. In addition to this,a fimdamental approach for computing the prediction probabilities is also proposed.Moreover, a new challenging issue named 'sense and stuck'was observed in the conventional approach.The proposed approach is validated by comparing the results achieved with the results of the conventional approach.However, to achieve the prediction probabilities,the pre-channel-state-information is a prerequisite,but it may be unavailable for particular scenarios;therefore,a modified selection method is introduced to avoid the sense and stuck problem.An algorithm to evaluate the throughput using the random,improved,and modified selection methods is presented with its space and time complexities.Furthermore,for additional improvement in the throughput of the CU,a new frame structure is introduced,in which the spectrum prediction and sensing periods are exploited for simultaneous transmission of data via the underlay spectrtun access technique (Approach-2).The simulated results of Approach-2 are compared with our pre-obtalned results of Approach-I,which confirm significant improvement in the throughput. | Prabhat Thakur Alok Kumar S.Pandit G.Singh S.N.Satashia | 2018 | Digital Communications and Networks2018,4,4: | 1 |
| 10 | 印度北部污染物对雨水中PH值的长期影响显示文摘在阿格拉和德里1963年与1965年夏季季风期间收集的雨水样品中的离子成份和 PH 值同这两个城市在1984年夏天季风期间所收集到的雨水样品分别进行比较,发现阿格拉和德里在二十年之后 PH 值分别降低2.8(9.1—6.3)和0.9(7.0—6.1),此期间两城市的工业化有了很大的发展。PH 值降低的主要原因是雨水中酸性成份大大增加,来自土壤的成份减少了。这是在印度第一次观察到污染物对雨水 PH 值的长期影响,但是这种影响与西方国家相比是比较慢的。 | L.T.Khemani G.A.Momin P.S.Prakasa Rao P.D.Safai G.Singh R.N.Chatterjee Prem Prakash 刘育民 聂明浩 陆贞芝 | 1993 | 江苏环境科技1993,,4: | 0 |

| 13 | Clinical features and management of ureteric stump syndrome:Single-centre experience and contemporary literature review显示文摘Dear editor,“Ureteric stump syndrome(USS)”is a rare entity(incidence 0.8%–1.0%)with left-over in situ distal-ureter being the culprit[[1],[2],[3]].The presentation may be recurrent urinary tract infection(UTI),flank/abdominal pain,or hematuria[1,4].Although only few of the patients require intervention(approximately 1.1%–10%)[[1],[2],[3]],either with open excision of the stump[[1],[2],[3]]or via minimally invasive endoscopic approach[5,6],prompt diagnosis is often delayed.During simple nephrectomy,dilemma exists whether to consider concomitant total ureterectomy to eliminate the future risk of USS[4],or to consider subtotal-ureterectomy along with nephrectomy[[1],[2],[3]].In this letter,we present a retrospective analysis of clinical presentation,diagnostic approach,and management of three patients of USS(Table 1)treated at our centre and try to solve all these dilemmas. | Krishnendu Biswas Abhishek G.Singh Arvind P.Ganpule Ravindra B.Sabnis Mahesh R.Desai | 2022 | Asian Journal of Urology2022,9,2: | 0 |
