Aromatic rice has become popular owing to its aroma. Growing demand for aromatic rice has spurred interest in the development of domestic cultivars that offer similar combinations of grain attributes such as texture, cooking characteristics, aroma, and taste. In this study, the most important agronomic attributes and aroma of 26 cultivars from Afghanistan, Iran, and Uzbekistan, and controls from Japan, Thailand, and India were characterized. Also $F_2$ populations derived from the cross between(Jasmine 85 aromatic$\times$Nipponbare non-aromatic) and(Jasmine 85$\times$Basmati 370 aromatic) were obtained. Tasting individual grains, cooking test, 1.7% KOH sensory test, and molecular marker analysis have been applied to distinguish between aromatic and non-aromatic rice. Diversity for some traits of agronomic importance, such as plant height was detected among countries, e.g. Afghan cultivars classified as tall, and Iranian and Uzbek intermediate and short, respectively. Differentiations of panicle, grain, leaf, basal internode, and culm dimension among rice cultivars, indicating the source of rice diversity in Central Asia. According to the results, 6 of 10, 2 of 7, and 0 of 6 of Afghan, Iranian, and Uzbek rice cultivars were scored as aromatic, respectively. Therefore, Afghan cultivars are a good source of aromatic rice germplasm for Central Asia. The expression between aromatic and non-aromatic, and aromatic and aromatic combinations has been evaluated. The observed segregation ratio of these crosses in the $F_2$ populations was tested by $x^2$ analysis against the expected ratio for a single gene. A segregation ratio of 3:1 between non-aromatic and aromatic combination has been detected, while segregation has not been detected between the aromatic and aromatic combinations. Also, parallel results were obtained from the tested aromatic rice cultivars. Thus, our results suggest that a single recessive gene controls aroma in all aromatic rice cultivars.

Implications of 3-Dimensional Printed Spinal Implants on the Outcomes in Spine Surgery

Fiani, Brian,Newhouse, Alexander,Cathel, Alessandra,Sarhadi, Kasra,Soula, Marisol The Korean Neurosurgical Society 2021 Journal of Korean neurosurgical society Vol.64 No.4

Three-dimensional printing (3DP) applications possess substantial versatility within surgical applications, such as complex reconstructive surgeries and for the use of surgical resection guides. The capability of constructing an implant from a series of radiographic images to provide personalized anatomical fit is what makes 3D printed implants most appealing to surgeons. Our objective is to describe the process of integration of 3DP implants into the operating room for spinal surgery, summarize the outcomes of using 3DP implants in spinal surgery, and discuss the limitations and safety concerns during pre-operative consideration. 3DP allows for customized, light weight, and geometrically complex functional implants in spinal surgery in cases of decompression, tumor, and fusion. However, there are limitations such as the cost of the technology which is prohibitive to many hospitals. The novelty of this approach implies that the quantity of longitudinal studies is limited and our understanding of how the human body responds long term to these implants is still unclear. Although it has given surgeons the ability to improve outcomes, surgical strategies, and patient recovery, there is a need for prospective studies to follow the safety and efficacy of the usage of 3D printed implants in spine surgery.

Objective Although laparoscopic surgery is a good substitute for laparotomy in reducing postsurgical pain, many patients complain of shoulder pain after laparoscopic surgery and require pain-relief. Post-operative pain management leads to increased patient satisfaction. Transcutaneous Electrical Nerve Stimulation (TENS) is a non-pharmacological, noninvasive modality that reduces pain by activating the descending inhibitory systems in the central nervous system. Given the importance of decreasing shoulder pain after gynecological laparoscopy, the current study aimed to investigate the management of shoulder pain in these patients using TENS. Methods This was a retrospective case-control study. A total of 112 women aged 18-45 years who experienced shoulder pain due to gynecologic laparoscopic surgery were included in the study. Patients were divided into TENS and control groups. In the TENS group, TENS was used twice for 20 minutes each, but in the control group, the patients received regular treatment. Patients were evaluated at intervals of 2, 4, 8, 24, 48, and 72 hours after laparoscopy for shoulder pain score. Results The results showed a significant decrease in visual analog scale scores at 2, 4, and 8-hour in the TENS group compared with the control group. At 24 hours evaluation, although the pain was reduced, the difference was not significant. At 48- and 72-hour assessment, all patients in each group reported zero score for severity of pain. Conclusion The findings suggest that TENS significantly reduces postoperative shoulder pain.
