2. Severity of target spot and gas-exchange in tomato cultivated under colored films
ABSTRACT The tomato target spot caused by Corynespora cassiicola may have an important economic impact on tomato production in tropical regions. The objective of this work was to study the effect of different colored plastic films on tomato target spot severity, gas-exchange, and fruit yield. Disease severity, photosynthetic rate, stomatal conductance, trans

4. Anti-Zika Virus Effects, Placenta Protection and Chemical Composition of Passiflora edulis Seeds Ethanolic Extract
Various beneficial biological activities have been reported for passion fruit (Passiflora edulis), grown in tropical and subtropical regions. However, no study has yet demonstrated its action against the Zika virus (ZIKV) infection. The present study aimed to investigate the anti-ZIKV of the ethanolic passion fruit seed extract (PFSE), from which, liquid chr

5. Bioactive compounds and antioxidant activity of fruit of temperate climate produced in subtropical regions
Abstract Temperate fruit species, originate from regions with cold winters and well-defined climatic seasons. These fruits are also produced in subtropical and tropical regions. The aim of this study was to determine the bioactive compounds and antioxidant activity of different fruit cultivars from fruit trees of temperate climate, such as peach, pear, quinc

6. Assessment of Total Attenuation and Adaptive Scheme for Quality of Service Enhancement in Tropical Weather for Satellite Networks and 5G Applications in Nigeria
Abstract The dynamic weather condition is a major concern for optimum channel utilization in recent times, especially at higher frequencies with larger bandwidth for 5G applications. Over the years, rain-induced attenuation among the hydrometeors has been linked as the major cause of signal impairment especially at the frequency, f ≥ 10 GHz. However, when

7. Sugar derived from genetically modified sugarcane
Abstract Sugar is an ancient food and currently one of the most used ingredients in human nutrition and in the food industry. In tropical regions, sugar is produced mainly from sugarcane, while temperate countries produce sugar preferably from sugar beets. Due to its widespread use, the forthcoming adoption of genetically modified (GM) sugarcane varieties ma

8. Diffuse skin rash in tropical areas: Dengue fever or COVID-19?,
Abstract There have been several clinical manifestations associated with SARS-CoV-2 infection since 2019, including dermatological signs and symptoms. In this article, the authors report a case of a previously healthy patient with COVID-19 who was mistakenly diagnosed with dengue fever due to a skin rash. By the time the patient's investigation was initiated

9. SARS-CoV-2 and arbovirus infection: a rapid systematic review
ABSTRACT BACKGROUND: The numbers of cases of arboviral diseases have increased in tropical and subtropical regions while the coronavirus disease (COVID-19) pandemic overwhelms healthcare systems worldwide. The clinical manifestations of arboviral diseases, especially dengue fever, can be very similar to COVID-19, and misdiagnoses are still a reality. In the

10. Fissuroma (Aigialaceae: Pleosporales) appears to be hyperdiverse on Arecaceae: evidence from two new species from southern Thailand
ABSTRACT Thailand and other tropical regions have high fungal diversity. Our investigation and examination of microfungi on palms (Arecaceae) revealed two new ascomycetous species of Fissuroma. Fissuroma arengae and F. wallichiae spp. nov. are introduced using morphological and phylogenetic evidence. The novel species have coriaceous ascomata, cylindrical-cl

11. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

12. Pollen types of Sapindaceae from Brazilian forest fragments: apertural variation
ABSTRACT Morphological variations in angiosperm pollen grains may aid in the differentiation of families, genera and species. Sapindaceae pollen morphology holds promise for the recognition of taxa of this cosmopolitan family, which is well distributed in tropical regions and possesses great morphological diversity. This study presents the pollen morphology
