Market integration is a metric for market efficiency, notably pricing efficiency. This paper examined the type and degree of market integration in Bangladesh using the latest available weekly rice market price data from the six district markets in Bangladesh from January 2014 to December 2018. The findings demonstrated that the wholesale price series of rice are stationary at first difference, but non-stationary at levels. The vector error correction model is then implemented after the Johansen-Juselius approach has been used to examine the cointegrating relationship between the various district markets. The negative and statistically significant coefficients of error correction term for the rice markets in the Barishal, Chattogram, and Sylhet districts show that short-run dynamics are convergent with longterm equilibrium. According to the estimated results of the error correction model, there is an equilibrium relationship between the rice markets in Dhaka with rice markets in Barishal, Chattogram, Dinajpur, and Khulna over the long run. In the short run, the calculated coefficient values, however, indicate that there is only a weak transmission of price changes from one district market to another within the same week.

Background: High risk HPV (HR-HPV) testing has been recommended as an effective tool along with cytology screening in identification of cervical intraepithelial lesions (CINs) and prevention of their progress towards invasive cervical cancer. The aim of this study was to assess the HR-HPV DNA status by Hybrid Capture 2 (HC2) assay in healthy asymptomatic women of North-East India. Materials and Methods: This study examined cervical cell samples of forty three (n=43) healthy women by HC2 assay. A High Risk HPV DNA kit (Qiagen) was used which can detect 13 high risk HPV types: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68. Results: The mean relative light units (RLU) for samples was in the range of 141-5, 94, 619. HR-HPV DNA was confirmed in 16% (7/43) of participant women samples. Among demographic and clinical parameters, menstrual irregularity (p=0.039) and infection history (p=0.028) has shown statistically significant differences between the HR-HPV-positive and negative groups. In the HR-HPV positive group, two women were confirmed for CINs after colposcopy and histopathologic examination. Conclusions: We suggest that there may be an association between irregular menstruation and infection history of the urogenital tract with HR-HPV DNA prevalence in North-East Indian asymptomatic women. HC2 assay can be a valuable tool for HR-HPV screening.

Background: Persistent infection of one or more of about 15 high-risk human papillomaviruses (HR-HPVs), most commonly HPV types 16/18, has a significant role in cervical cancer initiation and progression. There are limited data available from north-east India about HPV prevalence though this region has high incidence rates of cervical cancer. The aim of this study was to investigate the HPV genotypes prevalent in cervical cancer patients of north-east India. Materials and Methods: We analyzed 107 cervical cancer patient samples. Nested multiplex PCR assays were employed for detection of 13 high risk and 5 low risk HPV types. Results: HPV was confirmed in 105 samples. The presence of 6 'carcinogenic' HPV types, HPV-16 (88%), -18 (15%), -31(4%),-45 (3%), -59 (4%), -58(1%), and one non carcinogenic, HPV-6/11 (6%), was recorded. Among various demographic and clinical factors only tumour stage showed a statistically significant association with HPV type infection (P=0.019). Conclusions: We suggest that the most prevalent genotype is HPV-16 followed by HPV-18 in cervical carcinoma patients of the north-eastern region of India. Advanced tumour stage may be associated with increased possibility of harbouring multiple HPV genotypes.
