Biomedical and Environmental Sciences 2006;19(6):422-426
Objective To study the impacts of abundance of woodlice, termites, and mites on some functional aspects of soil in order to elucidate the specific role of soil fauna in improving soil fertility in desert. Methods Fauna-rich sites were selected as experimental sites and adjacent areas were taken as control. Soil samples were collected from both sites. Soil respiration was measured at both sites. The soil samples were sent to laboratory, their chemical and biochemical properties were analyzed.Results Woodlice showed 25% decrease in organic carbon and organic matter as compared to control site. Whereas termites and mites showed 58% and 16% decrease in organic carbon and organic matter. In contrast, available nitrogen (nitrate and ammonical both) and phosphorus exhibited 2-fold and 1.2-fold increase, respectively. Soil respiration and dehydrogenase activity at the sites rich in woodlice, termites and mites produced 2.5-, 3.5- and 2-fold increases, respectively as compared to their control values. Fauna-associated increase in these biological parameters clearly reflected fauna-induced microbial activity in soil. Maximum decrease in organic carbon and increase in nitrate-nitrogen and ammonical-nitrogen, available phosphorus, soil respiration and dehydrogenase activity were produced by termites and minimum by mites reflecting termite as an efficient soil improver in desert environment. Conclusion The soil fauna-associated changes in chemical (organic carbon, nitrate-nitrogen, ammonical-nitrogen, phosphorus) and biochemical (soil respiration, dehydrogenase activity) properties of soil improve soil health and help in conservation of desert pedoecosystem.

OBJECTIVEFractures of the femur are the most incapacitating fractures. For children aged 6-14 years, there is no clear consensus as to the preferred treatment. The conventional treatment of traction and casting is no longer recommended. We report our experience in titanium elastic nailing for treatment of paediatric femoral diaphyseal fractures.
METHODSThirty patients in the age group of 6-16 years with displaced diaphyseal femoral fractures were stabilized with titanium elastic nails. Patients were followed up clinically and radiologically for a minimum period of 1 year. The final results were evaluated using Flynn's criteria. Technical difficulties and complications associated with the procedure were also analysed.
RESULTSOverall results were excellent in 20 cases and satisfactory in 10 cases. No patient had poor result. The average hospital stay was 9 days. All the fractures healed with an average time to union of 6.86 weeks. The most common complication encountered was soft tissue irritation at the nail entry site seen in 6 cases. Clinically, lengthening was noticed in 4 cases, while no patient had shortening. Malalignment was seen in only 6 cases. Perioperative difficulties encountered were failure of closed reduction seen in 6 cases and corkscrewing of nails in one case.
CONCLUSIONTitanium elastic nails are a relatively easy to use, minimally invasive, physeal-protective implant system with high rate of good and excellent outcomes in children aged 6-16 years. Technical pitfalls can be eliminated by adhering to the basic principles.

AIMTo evaluate the possible antifertility activity of Sarcostemma acidum (Roxb) Voigt. stem extract in male rats.
METHODMale rats were given 70% methanol extract of S. acidum stem orally at dose levels of 50 and 100 mg/kg/day for 60 days. Fertility was evaluated with mating test. Sperm motility and sperm density in cauda epididymides were also assessed. Biochemical and histological analyses were performed on blood samples and on the reproductive organs.
RESULTSS. acidum stem extract resulted in an arrest of spermatogenesis without any systemic side effect. Sperm motility as well as sperm density was reduced significantly. Treatment caused a 80% reduction in fertility at the 50 mg dose and complete suppression of fertility at the 100 mg dose. There was no significant change in RBC and WBC count, hemoglobin, haematocrit, sugar and urea in the whole blood and cholesterol, protein and phospholipid in the serum. The protein and glycogen content of the testes, fructose in the seminal vesicle and protein in epididymides were significantly decreased. Cholesterol in the testes was elevated. Treatment at both of the doses caused a marked reduction in the number of primary spermatocytes (preleptotene and pachytene), secondary spermatocytes and spermatids. The number of mature Leydig cells was decreased, and degenerating Leydig cells was increased proportionately.
CONCLUSIONS. acidum stem extract arrests spermatogenesis in male rats without noticable side effects.

OBJECTIVES: The present study examined relationships between socioeconomic status (SES) and obesity and body mass index (BMI) as well as the effects of health-related behavioral and psychological factors on the relationships. METHODS: A cross-sectional population-based study was conducted on Korean adults aged 20 to 79 years using data from the 2001, 2005, and 2007 to 2009 Korea National Health and Nutrition Examination Survey. Multivariate logistic and linear regression models were used to estimate odds ratios of obesity and mean differences in BMI, respectively, across SES levels after controlling for health-related behavioral and psychological factors. RESULTS: We observed significant gender-specific relationships of SES with obesity and BMI after adjusting for all covariates. In men, income, but not education, showed a slightly positive association with BMI (p<0.05 in 2001 and 2005). In women, education, but not income, was inversely associated with both obesity and BMI (p<0.0001 in all datasets). These relationships were attenuated with adjusting for health-related behavioral factors, not for psychological factors. CONCLUSIONS: Results confirmed gender-specific disparities in the associations of SES with obesity and BMI among adult Korean population. Focusing on intervention for health-related behaviors may be effective to reduce social inequalities in obesity.

AIMTo evaluate the effect of an ethanolic extract of Semecarpus anacardium fruits on spermatogenesis in albino rats.
METHODSMale albino rats were fed with a 50 % ethanolic extract of Semecarpus anacardium fruit at 100 mg.kg(-1).day(-1), 200 mg.kg(-1).day(-1) and 300 mg.kg(-1).day(-1) for 60 days. Fertility test was performed after 60 days of treatment. Sperm motility and density were observed in the cauda epididymis. Biochemical and histological analyses of the blood and reproductive organs were done. Recovery of fertility was followed to evaluate the reversibility of drug action.
RESULTSS. anacardium fruit extract administration resulted in spermatogenic arrest in albino rats. The sperm motility and density was reduced significantly. The RBC and WBC counts, haemoglobin, haematocrit, blood sugar and urea were found to be within the normal range in the whole blood. The protein, cholesterol and glycogen in the testes and the fructose in the seminal vesicle were significantly decreased after the treatment. The fruit extract feeding caused marked reduction in the number of primary spermatocytes, secondary spermatocytes and spermatids. The number of mature Leydig cells was also decreased and degenerating cells increased proportionately.
CONCLUSIONS. anacardium fruit extract causes spermatogenic arrest in albino rats.

We have recently cloned a pathogen inducible blast resistance gene Pi-kh from the indica rice line Tetep using a positional cloning approach. In this study, we carried out structural organization analysis of the Pi-kh locus in both indica and japonica rice lines. A 100 kb region containing 50 kb upstream and 50 kb downstream sequences flanking to the Pi-kh locus was selected for the investigation. A total of 16 genes in indica and 15 genes in japonica were predicted and annotated in this region. The average GC content of indica and japonica genes in this region was 53.15% and 49.3%, respectively. Both indica and japonica sequences were polymorphic for simple sequence repeats having mono-, di-, tri-, tetra-, and pentanucleotides. Sequence analysis of the specific blast resistant Pi-kh allele of Tetep and the susceptible Pi-kh allele of the japonica rice line Nipponbare showed differences in the number and distribution of motifs involved in phosphorylation, resulting in the resistance phenotype in Tetep.

BACKGROUND:
As lung ultrasound (LUS) can be used to identify regional lung ventilation and collapse, we hypothesize that LUS can be better than auscultation in assessing lung isolation and determining double lumen tube (DLT) position.
METHODS:
A randomized controlled study was conducted in tertiary care cancer institute from November 2014 to December 2015, including 100 adult patients undergoing elective thoracic surgeries. Patients with tracheostomy, difficult airway and pleural-based pathologies were excluded. After anesthesia induction and DLT insertion, patients were randomized into group A (auscultation) and group B (LUS). Regional ventilation was assessed by experienced anesthesiologists using the respective method for each group. Final confirmation of DLT position with a bronchoscope was performed by a blinded anesthesiologist. Contingency tables were plotted to determine sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for each method.
RESULTS:
Data from 91 patients were analyzed (group A = 47, group B = 44). Compared with auscultation, LUS had significantly higher sensitivity (94.1% vs. 73.3%, P = 0.010), PPV (57.1% vs. 35.5%, P = 0.044), NPV (93.8% vs. 75.0%, P = 0.018), accuracy (70.5% vs. 48.9%, P = 0.036) and required longer median time (161.5 vs. 114 s, P < 0.001) for assessment of DLT position. Differences in specificity (55.6% vs. 37.5%, P = 0.101) and area under curve (0.748; 95% CI: 0.604–0.893 vs. 0.554, 95% CI: 0.379–0.730; P = 0.109) were not significant.
CONCLUSIONS
Compared to auscultation, LUS is a superior method for assessing lung isolation and determining DLT position.

Journal of Liver Cancer 2024;24(2):224-233
Background:
s/Aims: Hepatocellular carcinoma (HCC) is generally diagnosed at an advanced stage, which limits curative treatment options for these patients. Locoregional therapy (LRT) is the standard approach to bridge and downstage unresectable HCC for liver transplantation (LT). Atezolizumab-bevacizumab (atezo-bev) can induce objective responses in nearly one-third of patients; however, the role and outcomes of downstaging using atezo-bev remains unknown.
Methods:
In this retrospective single-center study, we included consecutive patients between November 2020 and August 2023, who received atezo-bev with or without LRT and were subsequently considered for resection/LT after downstaging.
Results:
Of the 115 patients who received atezo-bev, 12 patients (10.4%) achieved complete or partial response and were willing to undergo LT; they (age, 58.5 years; women, 17%; Barcelona Clinic Liver Cancer stage system B/C, 5/7) had received 3-12 cycles of atezo- bev, and four of them had received prior LRT. Three patients died before LT, while three were awaiting LT. Six patients underwent curative therapies: four underwent living donor LT after a median of 79.5 days (range, 54-114) following the last atezo-bev dose, one underwent deceased donor LT 38 days after the last dose, and one underwent resection. All but one patient had complete pathologic response with no viable HCC. Three patients experienced wound healing complications, and one required re-exploration and succumbed to sepsis. After a median follow-up of 10 months (range, 4-30), none of the alive patients developed HCC recurrence or graft rejection.
Conclusions
Surgical therapy, including LT, is possible after atezo-bev therapy in well-selected patients after downstaging.
