Alterations in plasma apolipoproteins in individuals with malaria infection and their potential roles in the pathogenesis are known but the link between the malaria parasite density and apolipoprotein A1 (apo-A1) level is insufficiently understood. This study was conducted to determine whether the plasma apo-A1 level is influenced by the degree of parasitaemia in malaria infections.
In a case-control study, a convenient sample of children aged 2-10 years with uncomplicated malaria cases (UMC), asymptomatic parasitaemia cases (APC) and healthy children without parasitaemia (HCP) was recruited. The cases consisted of 61 UMC and 21 APC, while the controls consisted of 24 HCP. Levels of apo-A1 was determined using immunoturbidimetric assay and compared among the different degrees of parasite density.
Of the 82 participants with parasitaemia, density was ≤1000/μL in 12, 1001-10000/μL in 21 and >10000/μL in 49 children. There was significant difference among the mean values of apolipoprotein A1 of the three groups, viz UMC [91.4 (95% CI 81.3, 101.5) mg/dL], APC [67.0 (95% CI 48.9, 84.9) mg/dL] and HCP [99.0 (95% CI 76.6, 121.3) mg/dL], p=0.029. Post-hoc analysis revealed that the mean plasma level of apo-A1 in HCP was significantly higher than APC by 32.0±12.4 mg/dL and UMC by 7.5±4.2 mg/dL. However, there were no differences in the mean apolipoprotein A1 levels among the three groups of parasite density.
The presence of parasitaemia causes a remarkable reduction in apolipoprotein A1 level that was not influenced by the degree of parasitaemia.

Malaria control strategies for a particular area largely depends on the correct identification of the mosquito species prevalent in that area. This study aimed to develop an android mobile app named 'Pictorial Indian anophelines key', which can be used to identify the 58 species of Indian female adult anophelines based on morphological characteristics.
The pre-requisite to use this app requires a minimum basic knowledge of mosquito morphological characteristics and features. The user needs to view the collected mosquito under a dissecting binocular microscope and has to select the observations on the app presented in the form of labelled picture format. The app uses a divide and conquer algorithm which narrows the selection from genus level to final identification of species.
The app is user-friendly, quick and it accurately identifies the mosquito species in a maximum of six consecutive clicks. The result displays a complete image of identified mosquito along with its quick identification features. It can be used for both subgenus Cellia and Anopheles.
This pictorial key-based mobile app could be helpful for entomologists, malariologists, researchers, public health workers as well as students in the quick and correct identification of anopheline mosquitoes prevalent in India which in turn could be helpful in devising appropriate approaches towards malaria control and prevention. The app can be modified as per future requirements.

To understand Wolbachia biology and its utility as a bio-control for vector mosquito's populations, we investigated its dissemination pattern in field in collected Ae. albopictus along with its maternal transmission efficacy over generations in regions of endemic dengue (DENV) transmission. Field collected Ae. albopictus were subjected to PCR for Wolbachia screening. Overall mean Wolbachia infection frequency in Ae. albopictus was found out to be 87.3% wherein a trend was observed in the pattern of maternal transmission across generations. χ2 for trend revealed a significant variation between Wolbachia infections and non-infections in Ae. albopictus generations. Linear regression analysis revealed the involvement of a strong negative correlation, implying that overall Wolbachia infection tends to decrease in places with high dengue cases.The reduction in Wolbachia infection frequency may be attributed to several environmental factors with the probability of being the cause for endemicity of dengue in the studied areas.This study reports on the transmission efficacy of naturally occurring Wolbachia in successive generations of Ae. albopictus and its correlation with dengue cases in clusters of Odisha, India. Studying the transmission trend of Wolbachia along with transovarial transmission of DENV might be indicative towards the interplay of Wolbachia infection in presence/absence of DENV.
Leishmaniasis, known as a disease with high prevalence proportion throughout the world, is caused by protozoan parasites. Visceral leishmaniasis is the most severe form of this condition reported sporadically from all regions in Iran. Between different diagnostic tests, serodiagnosis of this infection is of utmost importance in both humans and dogs. Although rK39 ELISA test has been extensively validated in endemic areas, there are currently challenges regarding a more appropriate serodiagnostic test.
A novel multi-epitope construct was designed consisting of highexposedB cell epitopes using eight important antigens of Leishmania infantum (Gp63, KMP-11, HSP70, CPA, H2A, H3, LACK and TRYP). Our artificial sequence, a Multi-epitope Recombinant Protein (MRP), was consequently produced and purified. Then, immunoreactivity was investigated by ELISA test and western blotting as well.
In the present study, the cutoff value (1.052) for the new MRP-ELISA was determined by receiver operator characteristic (ROC) curve analysis using 35 known positive and 20 known negative HVL sera previously tested for antibodies to L. infantum by DAT, showing a sensitivity of 93.1% and a specificity of 77.4%. The blotting test also showed a favorable band to detect visceral leishmaniasis.
According to the results, this new antigen had acceptable potential in detecting VL positive cases once western blotting was utilized, but the ELISA test did not proceed as expected for detecting true negative cases, probably due to some optimization issues.The present study is a promising start.

We present a locally recurrent case of dorsal PNET in the fifth decade of life after a prolonged disease-free interval of 10 years. The patient received radiation therapy in fairly large fields twice in his lifetime and was planned for third-time radiation to a few overlapping paraspinal areas over a period of three decades. Keeping in mind previous irradiations, possible target volume in proximity to organs at risk (OARs) patient was planned for consolidtive radiation using the most conformal technique available, which is proton beam therapy with image guided pencil beam scanning technique. Special dose constraints for the spinal cord and other OARs were set, and proton therapy plan was generated at our institute. When compared with parallelly generated intensity-modulated radiation therapy plan with the same dose prescription and dose constraints using helical tomotherapy, intensity-modulated proton therapy plan showed superior dosimetric benefit in terms of coverage and significant sparing of OARs.Immature gastric teratoma is an uncommon germ cell tumor of the stomach. A 6-month-old male child was born through full-term vaginal delivery. After 1 month presented with a history of abdominal distension and palpable mass along with a history of Malena for the past 10 days. Computed tomography scan showed the presence of a large well-defined multilobulated solid cystic lesion with multiple calcifications in the abdominopelvic region. Radiological findings were suggestive of germ cell tumors. The exploratory laparotomy findings showed a large tumor mass with variegated consistency arising from the lesser curvature of the posterior wall of the stomach. The total excision of mass and primary closure of the gastric wall was done. Histopathology of excised specimens showed immature teratoma of the stomach. The child is still on follow-up regularly visited as outpatient, doing well day-to-day activity. We report a very rare case of immature gastric teratoma in an infant on the basis of clinicoradiological and pathological findings.With substantial improvement in survival in cancer patients, the risk of radiation-induced malignancy in previously irradiated areas is increasingly possible. Both radiation-induced sarcomas and papillary thyroid carcinomas (PTCs) are well documented in literature. However, radiation-induced synchronous malignancies are rare, are often misdiagnosed, and presents with diagnostic and therapeutic challenges due to paucity of literature and lack of available guidelines. Here, we report a case of radiation-induced synchronous mandibular osteosarcoma and PTC in a previously treated carcinoma of base tongue with concurrent chemoradiation. He initially presented with an oral cavity mass, and during the course of the treatment was incidentally diagnosed with a synchronous PTC. It also establishes the indolent course of PTC, which often goes undiagnosed till the presentation with regional nodal metastasis. This report, to the best of our knowledge, is the first reported case of synchronous radiation-induced OSM and PTC.Although papillary serous cyst adenocarcinoma of the ovary is a common tumor, the incidence of ovarian-type papillary serous cyst adenocarcinoma in the testis is rare. Based on medical documents, there are only about 50 cases reported about testicular and paratesticular serous tumors.[1],[2],[3] Herein, we report a case of low-grade serous cyst adenocarcinoma of the testis that did unilateral orchiectomy and then came with retroperitoneal mass and lung metastasis. Cefodizime nmr Chemotherapy was well tolerated, and now, after 1 year, he does not have any complaint.We report a case of AML in a 29-year-old HIV-positive female on anti-retroviral therapy. She presented with bicytopenia, fever and easy fatiquability. Bone marrow examination revealed 77% blasts, which on flow cytometric immunophenotyping showed positivity for myeloid lineage markers and were negative for monocytic and lymphoid lineage markers. Although rare, AML is seen in HIV patients, therefore, in presence of persistent cytopenias, detailed hematological evaluation should be done so as to not miss/delay the AML diagnosis.
