Introduction. Undescended testis or cryptorchidism is detected in 3% of full-term male newborns, and in up to 33% of preemies. As the testicular descent may sometimes resolve spontaneously during first months of life, cryptorchidism is found in 1% of boys one year old. According to Consensus of Nordic experts in pediatric urology regarding cryptorchidism the optimal period for surgery is 12-18 months of age. The goal of this study was to identify the age of patients with congenital undescended testis at the time of surgery. Material and Methods. A retrospective study included all the cases of cryptorchid patients who had undergone orchidopexy in the period from 2007 to 2014. The patients? age and the place of residence were analyzed. Results. A total of 637 patients (722 orchidopexies) underwent the elective operative treatment of undescended testis during the observed period. The analysis revealed that only 144 (22.60%) of cryptorchid infants were operated on within their first 18 months of life. In the group of 359 patients from the urban environment, 101 (28.13%) were operated under the age of 18 months. Among the 278 patients from the rural environment, 43 (15.46%) were 18 months and younger at the time of surgery. Conclusion. The timing of surgical treatment of undescended testis in the study period was far from the recommended optimal time. It is evidently necessary to plan and provide additional information for pediatricians and parents about the current view on cryptorchidism and consequences of the late treatment.

Inguinal Hernia In Children

Aims and Objectives: To know the most common surgical problems in pediatric patients presented with inguino-scrotal swellings and management done routinely. Methodology: This study was carried out in the department of general surgery, Sharadaben hospital and pediatric surgery of VS hospital, Ahmedabad. The cases were studied for a period of about one year (January, 2017 to Dec, 2017) and all children below 12 years of age, presenting to us with inguinoscrotal swellings were included in this study. The information was analysed in terms of age, diagnosis, procedure carried out and outcome. Results: Amongst the 150 children under the age of 12 years, 143 patients were males and 7 were females. Among these 150, 52 cases were of hydrocoele, 70 cases of hernia (of which 63 were males and 7 were females), 25 cases of undescended testis and 3 cases of epididymo orchitis were documented. All cases underwent simple herniotomy for hernia and hydrocoele, orchidopexy for undescended testis. The length of hospital stay ranged from 2-4 days with mean of 2.46 days. 11 children in the study were documented to have short term complications, all of which were recognised in the hospital and managed with good results. Conclusion: Hernia and Hydrocoele in children are often congenital and diagnosed clinically (history and examination). Indirect inguinal hernia are more common than other groin hernias. Open herniotomy is the operation of choice for inguinal hernia in children.

The main goal of this article is to determine the optimal time period of boiler for biomass renewal, because its usage affects the financial situation of the firm in the form of costs. In this contribution is applied the method of operational research - the method of optimal time of machine renovation. The results of the analyses point to the optimal period of biomass boiler renovation before its service life in the 11th year. Operating costs are increasing about 9% after this time. By using this model there is ability to plan financial sources for buying new biomass boiler at 5500-15600€ on the market. The scientific benefit lies in the fact that the model is applicable to all types of equipment and machinery, in various industrial areas and in services and it is preventive instrument for financial planning for machine renovation.

Torsion of an undescended testis is uncommon. Torsion of a cryptorchid testicle presents a nonspecific symptomatology. Clinical suspicion indicates emergent surgical exploration, irrespective of Doppler ultrasound with its inherent false negative results. Management of the contralateral testis is controversial. We emphasize the need of a complete physical examination of the child who goes to the emergency room with nonspecific symptoms of abdominal pain and ipsilateral empty hemiscrotum to rule out torsion of a cryptorchid testicle. Herein, we report a one-year-old infant with missed torsion of undescended left testis.

Unilateral Cryptorchidism

Background: Cryptorchidism or undescended testis is an evolutionary defect where one or both testes fail to descend into the scrotum. HCG causes the testes to fail, possibly due to weight gain, an increase in testicular vasculature, and stimulating the testosterone and di-hydro-testosterone. The present study has been conducted to evaluate the therapeutic effects of HCG on patients with unilateral cryptorchidism. Methods: In a prospective descriptive study, 211 patients of 8 months to 7 years old with unilateral cryptorchidism whose parents refused surgery received HCG therapy. The patients were followed up 1 month, 3months, and 12 months after the first injection. They were examined in terms of the location of testes, possible relapses, sides of undescended testes, treatment complications, and HCG therapeutic results. Results: Four weeks after the first injection, 160 patients (75.12%) out of 211 cases had the descent of testes into the inguinal canal and the scrotum. 69.5% of non-palpable abdominal testes descended into the inguinal canal, 69.7% of patients with inguinal testes, 78% of patients with supra inguinal testes and 100% of patients with retractile testis experienced the descent of testes into the scrotum. Conclusion: The therapeutic response to HCG was successful in more than 50% of the cases in all the groups. Therefore, the need for performing surgical procedures on children with unilateral cryptorchidism would be decreased and they can be treated by a cost-effective and less invasive method. Moreover, at least one-year follow-up of the patients is required to ensure outcomes of the treatment.

Fruticin (amorphin) is a constituent of the fruit of the false indigo-bush (Amorpha fruticosa L.), which belongs to the class of rotenoid glycosides, and shows several interesting pharmacological activities. The aim of this study was to isolate and chemically characterize this natural product, as well as to determine the optimal period of the year for A. fruticosa fruits collection. Fruticin was obtained by re-crystallization of the precipitate that formed after partial evaporation of the extract, prepared by 3fold extraction of powdered plant material by chloroform - ethanol (1:1, v/v). The structure of the final product was determined by various techniques of instrumental analysis (NMR, UV and MS), and confirmed by comparing the obtained spectra with corresponding data in available literature. The content of fruticin in A. fruticosa fruit was determined by LC-DAD-MS, using the external standard method based on the constructed calibration curve. Limits of detection (LOD) and quantification (LOQ) were also determined. A substantial increase in fruticin content was observed during the ripening period (>50 %). It has also been established that the optimal time for fruit collection is mid-December. Obtained results indicate that the content of fruticin in the A. fruticosa fruit is highly dependable on the time of collection. Since the biosynthesis of secondary plant metabolites is influenced not only by the time of collection, but by numerous other factors as well, additional studies are needed to define, with greater certainty, the conditions that are necessary for design of prospective efficient and sustainable production process.

Practical Task

Modules relating to engineering disciplines mostly comprise laboratory hands on practical in order to demonstrate the application of theory in practice. Guided sheet is usually followed by the instructor while carrying out the practical and students are allowed to work as a team by following the instructions. Since it is a common practice in almost all engineering laboratories, students’ learning was investigated using two soil experiments in civil engineering technological programme in 2018. Interviews were conducted to search what students learn from the practical by recalling learned materials from sample of students after completion of the practical and the method adopted by the instructors were collected through the questionnaire. Analysis based on recalling learning showed that students remember observable aspects of practical task such as identification of apparatus and the testing procedure within one year but it does not assist them to learn theory and calculations though it has been totally covered during the practical lesson. It is noted that students highly involved in doing practical in laboratory rather than attending theory and calculation. Students’ active involvement in learning before the commencement of practical with the assistance of the instructor, observing physical outcomes while doing and searching additional information at the end through internet have showed better results. Preset process is found partially effective and learning on theory and calculation need to be improved to make the process success.

Timing Of Estrus

The timing of estrus synchrony between donor and recipient does is an important consideration in an embryo transfer program. Experiments were conducted to determine the optimal time of estrus synchrony between donor and recipient dairy goats used in a commercial nuclear transfer (NT) program. Donor and recipient synchronization was achieved by implanting either a 3-mg norgestomet ear implant (Crestar®, Intervet Int. B.V., Boxmeer, Holland) or a 300-mg progesterone vaginal implant (CIDR-G®, Pharmacia and Upjohn Ltd. Co., Auckland, NZ) on Day 0. A single 5mg intramuscular injection of prostaglandin (Lutalyse®, Pharmacia and Upjohn, Kalamazoo, MI, USA) was administered on Day 7. Recipients received a single 200–500IU intramuscular injection of PMSG (Calbiochem, LaJolla, CA, USA) on Day 13. Alternatively, starting on Day 12 donors received twice daily intramuscular injection (64mg/day) of FSH (Folltropin®, Vetrepharm, Ontario, Canada) over four consecutive days. On Day 15 the implants were removed from both donors and recipients and the animals were mated several times daily to vasectomized bucks over two consecutive days. In Experiment 1, estrus synchrony or asynchrony was achieved by removing the implant from recipients at the same time or 12h later than donors, respectively. In Experiment 2, only estrus asynchrony was utilized and was achieved by removing the implant from recipients either 12 or 18h later than donors. In vivo-ovulated MII oocytes surgically recovered from superovulated donors on Day 17 were enucleated and reconstructed with transfected caprine fetal or adult skin cells or transgenic adult skin cells. Couplets were simultaneously fused, activated, and then cultured in SOF/BSA for 48h at 38°C. Two-to-eight-cell NT embryos at 48h post-fusion and activation were surgically transferred to the oviducts of surrogate recipients with similar implant types and PMSG doses. Pregnancies were determined by ultrasonography starting at approximately Day 28 post-fusion and activation and then monitored weekly. In Experiment 1, there were significantly more pregnant asynchronous recipients compared with synchronous recipients (6 of 24 v. 12 of 124 does, respectively). While there were no significant differences, more offspring were produced per embryo transferred to asynchronous recipients compared with synchronous recipients (5 of 135 v. 11 of 690 offspring per embryo transferred, respectively). In Experiment 2, while not significant, there were more pregnant +12-h asynchronous recipients compared with +18-h asynchronous recipients (16 of 72 v. 5 of 36 does, respectively). Again, while there were no significant differences, more offspring were produced per embryo transferred to +12h compared with +18h asynchronous recipients (11 of 424 v. 3 of 224 offspring per embryo transferred, respectively). These results suggest that asynchrony of estrus between recipients and donors is more beneficial in a commercial caprine NT program, and that +12h may be a more optimal period of asynchrony for recipient does receiving NT embryos.

Ultrastructural studies of gerbil testes after vasectomy have been described (2S3). The present study was undertaken to obtain additional information on the effects of vasectomy in the fine structures of the epididymis of the Mongolian gerbils (Meriones unguiculatus). The animals were subjected to vasectomy or sham operation at intervals up to one year. An incision was made on the ventral side of the animal just above the scrotum, and about one centimeter of each vas deferens was removed and the ends were firmly ligated. The cauda epididymis of vasectomized and sham operated animals was fixed for two hours in Karnovsky's fixative. Following a rinse in buffer, the tissue was post fixed for one hour in osmium tetroxide, dehydrated, and embedded in Epon 812. The sections were stained with uranyl acetate followed by Reynolds' lead citrate, and examined with a Philips 201 transmission electron microscope operating at 60 kV.
