A Rare Parasitic Infection from the Common Cockroach: A Case of Lophomonas Blattarum from a Tertiary Center in Kerala.

Immunocompromised patients are prone to various opportunistic infections. Most of the infections are easily detectable through staining, culture, and polymerase chain reaction techniques. Nevertheless, it is also important to have wet smear examinations of samples.

Vanillic acid mitigates hyperinsulinemia induced ER stress mediated altered calcium homeostasis, MAMs distortion and surplus lipogenesis in HepG2 cells.

Hyperinsulinemia (HI) induced insulin resistance (IR) and associated pathologies are the burning and unsolvable issues in diabetes treatment. The cellular, molecular and biochemical events associated with HI are not yet elucidated. Similarly, no focused research on designing therapeutic strategies with natural products for attenuation of HI are seen in literature.

Artificial germination of Enterocytozoon hepatopenaei (EHP) spores induced by ions under the scanning electron microscope.

Effect of ammonia stress on immune variables of Pacific white shrimp Penaeus vannamei under varying levels of pH and susceptibility to white spot syndrome virus.

Of late, Pacific white shrimp Penaeus vannamei culture has intensified globally and is a major contributor to the cultured shrimp produced worldwide. Intensification of its culture has led to elevated ammonia concentration during grow-out. Ammonia toxicity is a function of water pH, temperature, salinity and beyond the optimum range, creates stress to cultured aquatic species which can reduce growth, increase susceptibility to diseases and eventually mortality.

Development of antiviral gene therapy for Monodon baculovirus using dsRNA loaded chitosan-dextran sulfate nanocapsule delivery system in Penaeus monodon post-larvae.

In the present study, a suitable carrier system was developed for the delivery of dsRNA into Penaeus monodon (P. monodon) post larvae to silence the Monodon baculovirus (MBV) structural gene of p74. The carrier system was developed by layer by layer adsorption of oppositely charged chitosan-dextran sulfate, on charged silica nanoparticles.

Development of SYBR Green based real time PCR assay for detection of monodon baculovirus in Penaeus monodon.

Shrimp farming is one of the most important aquaculture activities. Expansion and intensification of shrimp farming has been accompanied with the outbreak of diseases, which threaten the development and sustainability of the industry. Viral diseases are the major challenges faced by shrimp farming industries.

Laem-Singh Virus: A Probable Etiological Agent Associated with Monodon Slow Growth Syndrome in Farmed Black Tiger Shrimp (Penaeus monodon).

Among the emerging diseases in shrimp aquaculture, monodon slow growth syndrome (MSGS) is a major concern in South and Southeast Asia. Shrimp farming in Thailand was severely affected during 2000-2002 due to MSGS, which caused an economic loss, of about US$ 300 million. MSGS is characterized by abnormally slow growth with coefficients of size variation of >35 %, that has impacted P.

Viral metagenomics: a tool for virus discovery and diversity in aquaculture.

Viruses are abundant biological entities on earth and the emergence of viral pathogens has become a serious threat to aquaculture and fisheries worldwide. However, our response to viral pathogens has been largely reactive, in the sense that a new pathogen is usually not discovered until it has already reached epidemic proportions. Current diagnostic methods such as PCR, immunological assays and pan-viral microarrays are limited in their ability to identify novel viruses.

A rare case of the lenz syndrome.

We are reporting here, a case of the Lenz syndrome in a neonate who was brought to the Paediatric OPD, Kasturba Medical College Hospital, Attavar, Mangalore India, with the complaints of poor suckling since birth and abnormal facial features. Altogether, the characteristic congenital abnormal findings in Lenz syndrome, which comprise of microophthalmia, ear anomalies, microcephaly, skeletal and digital deformities, and urogenital malformations were observed, with an exception of a dental anomaly. Dental abnormalities were not pertinent, as the patient was a neonate.

Enrichment and identification of large filamentous sulfur bacteria related to Beggiatoa species from brackishwater ecosystems of Tamil Nadu along the southeast coast of India.

Beggiatoa species are filamentous sulfide-oxidizing bacteria belonging to the family Beggiatoaceae that contains several largest bacteria known today. These large sulfur bacteria occur in diverse ecosystems and play an important role in the global sulfur, nitrogen and phosphorus cycle. In this study, sediment samples from brackishwater shrimp culture ponds and other brackishwater ecosystems from Tamil Nadu, southeast coast of India, were enriched for Beggiatoa species.

Total synthesis and antifungal activity of (2S,3R)-2-aminododecan-3-ol.

We report the total synthesis of (2S,3R)-2-aminododecan-3-ol has been achieved starting from commercially available 10-undecenoic acid. The key steps involved are Sharpless asymmetric epoxidation, Miyashita's boron-directed C-2 regioselective azidolysis, generated the asymmetric centers and in situ detosylation and reduction of azido tosylate. The antifungal activity of the synthesized (2S,3R)-2-aminododecan-3-ol was evaluated on several Candida strains and was comparable to miconazole, a standard drug.

Comparative efficacy of double-stranded RNAs targeting WSSV structural and nonstructural genes in controlling viral multiplication in Penaeus monodon.

RNA interference (RNAi) is a potential strategy to control shrimp viral diseases, including the white spot disease caused by White Spot Syndrome Virus (WSSV). Selection of genes for targeting is an important criterion. We have compared the efficacy of dsRNAs targeting structural (vp28 and vp281) and nonstructural genes (rr1 and dnapol) of WSSV in controlling viral multiplication in Penaeus monodon.

Supra dietary levels of vitamins C and E enhance antibody production and immune memory in juvenile milkfish, Chanos chanos (Forsskal) to formalin-killed Vibrio vulnificus.

Juveniles of milkfish, Chanos chanos (Forsskal), were fed two independent supra dietary levels of vitamins C (500 and 1500 mg kg(-1) feed, T1 and T2) and E (50 and 150 mg kg(-1), T3 and T4). Milkfish fed diets with supra (in addition to the vitamins present in the control diet) and normal levels (T5 containing 90 and 1.2mg of vitamins C and E, respectively, kg(-1) of feed) of vitamins were immunized (ip) with formalin-killed Vibrio vulnificus (FKVV).
