Asian Pacific Journal of Tropical Biomedicine 2014;(z1):22-26
Plants are used as medicine since ancient time, in organized (Ayurveda, Unani & Siddha) and unorganized (folk, native & tribal) form. In these systems, drugs are described either in Sanskrit or vernacular languages. Avartani (Helicteres isora Linn.) is a medicinal plant which is used in several diseases. It is commonly known as Marodphali, Marorphali, Enthani etc. due to screw like appearance of its fruit. Avartani is used as a folk medicine to treat snake bite, diarrhoea and constipation of new born baby. In the research, antioxidant, hypolipidaemic, antibacterial and antiplasmid activities, cardiac antioxidant, antiperoxidative potency, brain-antioxidation potency, anticancer activity, antinociceptive activity, hepatoprotective activity, anti-diarrheal activity and wormicidal activity in this plant were reviewed.

Background & Objective: Transthyretin (TTR) has been associated with spinocerebellar ataxia (SCA)
by several independent case reports. Coexistence of TTR and SCA mutations, overlapping clinical
symptoms as well as altered levels of TTR in SCA patients suggest a correlation between TTR and
SCA. To our knowledge, no large cohort based study has been attempted to examine the association of
SCA with polymorphism in TTR gene. Here, we chose to investigate TTR variations in SCA patients
(n=266) and controls (n=192) of North Indian ethnicity. Methods: We sequenced the exons including
exon-intron boundaries of TTR gene in 55 patients and 55 controls. We observed four variations
which were further genotyped by single base extension method (SNaPshot) in a larger cohort (SCA
patients n=211 and controls n=137). Results: A novel synonymous variation c.372 C>G in exon 4
was detected in heterozygous condition in one control sample. We found nominal association for
rs1800458 (Gly6Ser), with SCA (p-value < 0.05) which did not remain after Bonferroni correction
for multiple tests. Pairwise linkage disequilibrium (LD) analysis revealed no LD between studied
SNPs. Further, we employed two-marker sliding window analysis and observed a weak association of
haplotype AT of rs1800458 and rs1667251 with SCA patients (p-value <0.05) which was not retained
after Bonferroni correction.
Conclusion: Our data suggests no association of genetic variations of TTR in SCA pathology.

The emerging protozoan parasites Cryptosporidium, Cyclospora cayetanensis and Isospora belli have altered the etiological spectrum of diarrhea. The progressive decline in CD4 cell count in AIDS patients and lack of active immunity in the face of exposure to contaminated food and water in young children make these groups of persons particularly susceptible to protracted and severe diarrhea caused by the above parasites. Cryptosporidiosis is caused by human as well as several zoonotic species. The present study was undertaken to examine the prevalence of Cryptosporidium species, C. cayetanensis and I .belli among these two susceptible populations in comparison with adult immunocompetent individuals with diarrhea and to identify the Cryptosporidium species prevalent in these populations. A total of 447 children under the age of 5 years, 175 HIV-seropositive adults and 200 HIV seronegative adults with diarrhea attending tertiary care hospitals located in the twin cities of Secunderabad and Hyderabad in South India were included in the study. Single fecal samples were collected. Wet mounts and modified Ziehl Neelsen stained smears made from concentrated fecal specimens were screened microscopically for oocysts of Cryptosporidium, Cyclospora cayetanensis and Isospora belli. DNA extracted from fecal samples positive for Cryptosporidium was subjected to PCR RFLP for species identification. Cryptosporidium was detected in all the three groups, I.e. children (8.7%), HIV-seropositive adults (6.85%), and HIV-seronegative adults (1%). Isospora and Cyclospora were detected only among HIV- seropositive persons at a frequency of 16% and 1% respectively. C. hominis (71.7%) and C. parvum (18.9%) were the only 2 species of Cryptosporidium detected.

Late vascular complications involving aorta are rare but devastating adversities following anterior thoracic spine operations are present. The current article describes our experience with one such patient who had an iatrogenic pseudoaneurysm of the thoracic aorta, mimicking infection. The patient was treated successfully following concomitant efforts by multidisciplinary experts with shunting. We wish to highlight upon the significance of recognizing the possible sinister consequences of a dangerously prominent spinal implant and the role of a suspicious surgeon in identifying these menacing complications at the right time.

It is well established that there is a heritable element of susceptibility to chronic human ailments, yet there is compelling evidence that some components of such heritability are transmitted through non-genetic factors. Due to the complexity of reproductive processes, identifying the inheritance patterns of these factors is not easy. But little doubt exists that besides the genomic backbone, a range of epigenetic cues affect our genetic programme. The inter-generational transmission of epigenetic marks is believed to operate via four principal means that dramatically differ in their information content: DNA methylation, histone modifications, microRNAs and nucleosome positioning. These epigenetic signatures influence the cellular machinery through positive and negative feedback mechanisms either alone or interactively. Understanding how these mechanisms work to activate or deactivate parts of our genetic programme not only on a day-to-day basis but also over generations is an important area of reproductive health research.

OBJECTIVETo report a case series of six neglected cervical spine dislocations without neurological deficit, which were managed operatively.
METHODSThe study was conducted from August 2010 to December 2011 and cases were selected from the out-patient department of Postgraduate Institute of Medical Education and Research, India. The patients were in the age group of 30 to 50 years. All patients were operated via both anterior and posterior approaches.
RESULTSDuring the immediate postoperative period, five (83.33%) patients had normal neurological status. One (16.67%) patient who had C5-C6 subluxation developed neurological deficit with sensory loss below C6 level and motor power of 2/5 in the lower limb and 3/5 in the upper limb below C6 level.
CONCLUSIONThere is no role of skull traction in neglected distractive flexion injuries to cervical spine delayed for more than 3 weeks. Posterior followed by anterior approach saves much time. If both approaches are to be done in the same sitting, there is no need for instrumentation posteriorly. But if staged procedure is planed, posterior stabilization is recommended, as there is a risk of deterioration in neurological status.

In recent years, nanotechnology has revolutionized global healthcare and has been predicted to exert a remarkable effect on clinical medicine. In this context, the clinical use of nanomaterials for cancer diagnosis, fertility preservation, and the management of infertility and other pathologies linked to pubertal development, menopause, sexually transmitted infections, and HIV (human immunodeficiency virus) has substantial promise to fill the existing lacunae in reproductive healthcare. Of late, a number of clinical trials involving the use of nanoparticles for the early detection of reproductive tract infections and cancers, targeted drug delivery, and cellular therapeutics have been conducted. However, most of these trials of nanoengineering are still at a nascent stage, and better synergy between pharmaceutics, chemistry, and cutting-edge molecular sciences is needed for effective translation of these interventions from bench to bedside. To bridge the gap between translational outcome and product development, strategic partnerships with the insight and ability to anticipate challenges, as well as an in-depth understanding of the molecular pathways involved, are highly essential. Such amalgamations would overcome the regulatory gauntlet and technical hurdles, thereby facilitating the effective clinical translation of these nano-based tools and technologies. The present review comprehensively focuses on emerging applications of nanotechnology, which holds enormous promise for improved therapeutics and early diagnosis of various human reproductive tract diseases and conditions.

Objectives:
Regions with limited sanitation facilities have higher rates of infections with various enteric pathogens. It is therefore important to identify different hosts and their relative contribution to pathogen shedding into the environment, and to assess the subsequent health risks to humans.
Methods:
In this study, human faecal (n=310), animal faecal (n=150), and environmental (soil) samples (n=40) were collected from the same locality and screened for selected enteric pathogens by immunochromatography and/or polymerase chain reaction.
Results:
At least 1 microbial agent was detected in 49.0%, 44.7%, and 40.0% of the samples from human, animals, and soil, respectively. Among humans, rotavirus was predominantly detected (17.4%) followed by enteropathogenic Escherichia coli (EPEC) (15.4%), Shigella (13.8), and Shiga toxin-producing E. coli (STEC) (9.7%). Among animals, STEC was detected most frequently (28.0%), and EPEC was the major enteric pathogen detected in soil (30.0%). The detection rate of rotavirus was higher among younger children (≤2 years) than among older children. Single infections were more commonly detected than multiple infections in humans (p<0.01), unlike the observations in animal and soil samples. For diarrhoeagenic E. coli and Shigella, most of the human and animal isolates showed close relatedness, suggesting possible cross-infection between humans and domesticated animals in the area studied.
Conclusions
The present study provides an improved understanding of the distribution of major enteric pathogens coexisting in humans and animals in the region, thereby suggesting a high potential for possible transmission among livestock and communities residing in the studied locality.
