Trees outside forests are an underestimated resource in a country with low forest cover.

Trees outside forests (TOF) are an underrepresented resource in forest poor nations. As a result of their frequent omission from national forest resource assessments and a lack of readily available very-high-resolution remotely sensed imagery, TOF status and characterization has until now, been unknown. Here, we assess the capacity of openly available 10 m ESA Sentinel constellation satellite imagery for mapping TOF extent at the national level in Bangladesh. In addition, we estimate canopy height for TOF using a TanDEM-X DEM. We map 2,233,578 ha of TOF in Bangladesh with a mean canopy height of 7.3 m. We map 31 and 53% more TOF than existing estimates of TOF and forest, respectively. We find TOF in Bangladesh is nationally fragmented as a consequence of agricultural activity, yet is capable of maintaining connectedness between remaining stands. Now, TOF accounting is feasible at the national scale using readily available datasets, enabling the mainstream inclusion of TOF in national forest resource assessments for other countries.

LncRNAs as Potential Therapeutic Targets in Thyroid Cancer.

Thyroid cancer (TC) is the most common cancer of endocrine system. TC can be subdivided into 4 different entities, papillary, follicular, medullary and anaplastic thyroid cancer. Among them, anaplastic thyroid cancer has the poorest prognosis. Exploring new therapeutic approach may entail favorable prediction as well as increasing overall survival rate of patients. Long non-coding RNAs (lncRNAs), have vast implications in different cancer types. Although they are not transcribed into proteins, they can act as a harness in regulating a plethora of biological functions. They have been implicated in a decisive role in gene expression via modulation of both coding and non-coding RNAs. This article discuss the multi-facet role of lncRNA in thyroid cancer biology.

Study of hematological indices in tannery workers exposed to chromium in Sheikhupura (Pakistan).

Chromium (Cr), being an excellent tanning agent, is widely used in the leather industry and tannery workers (TW) are exposed to it either in the form of inorganic Cr(III) compounds or Cr bound to proteins (leather dust) in the process of leather production. During the present study, the effect of Cr on the hematological indices in TW was evaluated. In this study, hematological indices of 92 male TW aged 20-60 years were compared with 79 control males who hardly had a chance of exposure to chromium. Both groups were subdivided into four age groups with an interval of 10: group A, 20-29 years; group B, 30-39 years; group C, 40-49 years; group D, 50-60 years. Total erythrocyte count (TEC) was significantly lower (p < 0.05) in TW of age group A, B and C than control subjects. Packed cell volume (PCV) was significantly higher (p < 0.05) in TW of age group B while mean corpuscular hemoglobin (MCH) was significantly lower (p < 0.05) in TW of age group D. Within the TW, MCH was significantly lower (p < 0.05) in the age group D as compared to age group A and B. No significant changes were observed in the values of hemoglobin, mean corpuscular volume and mean corpuscular hemoglobin concentration between TW and control individuals. The low values of TEC, PCV and MCH might be a result of chromium exposure in the tannery workers and may act as indicators of chromium toxicity.
