Water vapor thermal therapy (Rezum) is a novel, minimally invasive surgical technology used to treat lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). The objective of this systematic review is to evaluate the latest efficacy and safety profile of Rezum in patients with LUTS secondary to BPH. PubMed/MEDLINE and the Cochrane Library databases were systematically searched, in accordance with the PRISMA statement, for relevant articles in the English language till 1 August 2021. Randomized and nonrandomized studies that evaluated urinary outcomes and/or adverse events were deemed eligible. Nineteen studies (N = 1942), published in 25 articles, were included. International Prostate Symptom Score (IPSS), quality of life (QoL), and maximum urinary flow rate (Qmax) significantly improved as early as 1 month postoperatively and remained durable for up to 5 years. Significant median percent improvements in IPSS, QoL, and Qmax at 3 months were 51%, 51%, and 66%, respectively. Patients with obstructive median lobes, large prostates (>80 g), small prostates (<30 g), and urinary retention also experienced significant relief in LUTS, with 83% of urinary retention patients becoming catheter independent at a median of 14 days. Most adverse events were transient and nonserious and occurred in 0% to 76% of patients (median 29%), with de novo erectile dysfunction rates ranging between 0% and 3.1%. Surgical retreatment rate ranged between 4.4% and 7.5% at 5 years postoperatively. Rezum provides durable improvements in symptoms, irrespective of prostate volume and urinary retention status, and has low rates of sexual dysfunction.

This study was planned to determine the relationship between semen quality parameters and the levels of biochemical constituents of seminal plasma of Teddy (Capra hircus) buck semen. For this purpose, semen ejaculates were collected from five mature healthy Teddy bucks. All the experimental bucks were kept under natural environmental conditions. Semen was collected twice in a week for the duration of 6 weeks by Artificial Vagina (AV) in the breeding season (February-April). Two successive ejaculates of single buck were pooled at time of collection, and a total of 60 semen samples were processed for semen analysis. Sperm per cent motility, sperm concentration, dead sperm percentage, morphological abnormal spermatozoa, plasma membrane integrity were correlated with biochemical constituents of seminal plasma. The mean per cent motility (89.18% ± 0.37%), sperm concentration (1.86 ± 0.04 × 10 /ml), dead sperm percentage (8.08% ± 0.29%), morphological abnormal spermatozoa (6.05% ± 0.29%) and plasma membrane integrity (88.22% ± 0.34%) were recorded. The seminal plasma contained Na (144.12 ± 1.59 mEq/L), K (27.38 ± 0.49 mEq/L), Cl (65.73 ± 0.45 mEq/L), Ca (9.34 ± 0.22 mg/dl), P (19.32 ± 0.97 mg/dl), aspartate aminotransferase (AST; 26.48 ± 1.30 IU/L), alanine aminotransferase (ALT; 168.47 ± 5.18 IU/L), lactate dehydrogenase (LDH; 215.98 ± 6.06 IU/L), albumin (1.90 ± 0.10 g/dl), globulins (2.08 ± 0.11 g/dl) and total protein (3.98 ± 0.20 g/dl). The collected data were analysed by applying Pearson's correlation coefficients. Dead sperm percentage had negative correlation with sodium (r = -.278, p < .05), albumin (r = -.294, p < .05), globulin (r = -.266, p < .05) and total protein (r = -.295, p < .05). Phosphorus was negatively associated with sperm concentration (r = -.262, p < .05). AST was negatively correlated with plasma membrane integrity (r = -.292, p < .05). It was concluded that most of the semen quality parameters of Teddy bucks were positively correlated with biochemical constituents, but opposite trends were found in case of dead sperm percentage. The seminal biochemical constituents dynamically interact with each other.

As more increase in usage of communications and developing them more user friendly. While developing those communications, we need to take care of security and safety of user's data. Many researchers have developed many complex algorithms to maintain security in user's application. Among those one of the best algorithms are cryptography based, in which user will be safe side mostly from the attackers. We already had some AES algorithm which uses very complex cryptographic algorithm to increase the performance and more usage of lookup tables. So the cache timing attackers will correlates the details to encrypt the data under known key with the unknown key. So, for this we provide an improvised solution. This paper deals with an extension of public-key encryption and decryption support including a private key. The private key is generated with the combination of AES and ECC. In general AES, key length is 128 bits with 10 times of iterations. But with this, users won't get efficient security for their operations, so to increase the security level we are implementing 196-bit based encryption with 12 times round-key generation iterations. By this enhancement, we can assure to users to high level security and can keep users data in confidential way. Keyword:AES Crypto-system EC cipher text Public and private keys Random-key

The objective of this study was to investigate the toxic effects of arsenic on testicular measurements and histology of adult Teddy goats bucks and to examine whether these toxic effects are scavenged by vitamin E. Twelve adult Teddy goat bucks were divided randomly into three groups, A, B and C. Group A was kept as control, the B was given sodium arsenite 5 mg/kg BW per day, and group C was fed with vitamin E 200 mg/kg BW per day + arsenic 5 mg/kg BW per day. This treatment was continued for 84 days. Analysis of data revealed that the testicular measurements (scrotal circumference, width, length and weight) were significantly reduced in arsenic-treated animals, whereas there were ameliorating effects of vitamin E on these parameters. The major histopathological changes were present in the form of loss of germinal epithelium, atrophy of Leydig cells and vacuolations. Vitamin E in combination with sodium arsenite increased the active spermatogenesis as well as restoration of germinal epithelium. It can be concluded from the present findings that sodium arsenite causes toxicity in the male reproductive system of Teddy goat bucks with major changes in parenchyma of testes. Supplementation of vitamin E has protective effects on the toxicity of sodium arsenite on the reproductive system of male Teddy goat bucks.

Today the wireless sensor networks (WSN) play a crucial role in wireless technology in various domains like military, medicine, communications etc. The energy conservation is the crucial factor in the WSN. The WSN is a system which has more number of nodes in which various sensors are fabricated on the nodes to monitor various factors of the given task. These nodes will form a network by connecting the one to other for the effective communication between the nodes, and sends the whole information to the base station (BS). As the nodes which we use for the WSN are of low cost and are battery operated. The main drawback is replacement of the battery in the WSN. The main goal is to conserve the energy consumption in WSN and also to balance the load on WSN. For this many protocols are designed like LEACH, PEGASIS, PEDAP, etc. in those balancing the load and time delayed. some drawbacks are there. So we proposed a protocol so called “Tree Based Energy Balancing routing Protocol by Self Organizing” (TEBRSO), in which instead of routing tables a routing tree will be used for routing from nodes to base station (BS), which chooses one root/control node for the broadcasting messages to the selected sensor nodes. By this protocol we can save the energy consumption in WSN and can extend the life time of it. The performance of this protocol is better when we compare with other energy saving protocols.
