Some biological studies on Hypnea pannosa J. Ag.

The present investigation focused on studying the toxicity, analgesic, behavioral and anti-emetic activities of the ethanol extract of Hypnea pannosa. The ethanol extract caused 100% lethality at the doses of 250 and 500 mg/kg. Significant analgesic and central depressant effects were observed from 150 mg/ kg dose. The extract at 200 mg/kg dose exhibited significant anti-emetic effect, when compared to standard drug.Key words: Hypnea pannosa, toxicity, analgesic, behavioral, anti-emetic activities, crude extract

Effect of rainfall patterns on concentration of CO2, soil temperature and matric suction for acidic barren soil

This study is based on field monitoring of a soil-atmosphere toward on acidic barren soil. CO2 in the cavity are dependent on climatic parameters, mainly on the outdoor temperature during rainfall. Observations were taken over a longer period of time. Maximum CO2 values in the barren slope are reached in the warmest months and are in accordance with soil CO2 values. The maximum CO2 concentration in the barren slope is 3022 ppm on average, while the minimum is 2438 ppm. To describe the field findings, CO2 production and diffusion experiments related to the soil behavior were developed. The results showed that the soil CO2 production increases as the soil temperature and matric suction increase. The relationship between the gas diffusion coefficient and soil water suction is necessary data (i.e water evaporation or CO2 evolution above the soil surface)

Infectious diseases epidemic threats and mass gatherings: Refocusing global attention on the continuing spread of the Middle East Respiratory syndrome coronavirus (MERS-CoV)

Media and World Health Organization (WHO) attention on Zika virus transmission at the 2016 Rio Olympic Games and the 2015 Ebola virus outbreak in West Africa diverted the attention of global public health authorities from other lethal infectious diseases with epidemic potential. Mass gatherings such as the annual Hajj pilgrimage hosted by Kingdom of Saudi Arabia attract huge crowds from all continents, creating high-risk conditions for the rapid global spread of infectious diseases. The highly lethal Middle Eastern respiratory syndrome coronavirus (MERS-CoV) remains in the WHO list of top emerging diseases likely to cause major epidemics. The 2015 MERS-CoV outbreak in South Korea, in which 184 MERS cases including 33 deaths occurred in 2 months, that was imported from the Middle East by a South Korean businessman was a wake-up call for the global community to refocus attention on MERS-CoV and other emerging and re-emerging infectious diseases with epidemic potential. The international donor community and Middle Eastern countries should make available resources for, and make a serious commitment to, taking forward a "One Health" global network for proactive surveillance, rapid detection, and prevention of MERS-CoV and other epidemic infectious diseases threats

Performance Analysis in Quantitative Traits of Local Chickens (Gallus gallus sp.) In Kediri Regency East Java

This study aimed to determine the phenotypic diversity of the quantitative characteristics and the results of the analysis of kinship relationships of local chickens in Kediri by using 60 adult male local chickens. Data were obtained by directly observing the quantitative characteristics according to the variables: head length, chest-length, wing length from right to left, shank length, back length, neck circumference, and chest circumference. The results showed that the majority of phenotypes were from local chickens in Kediri, consisting; of a wing length of 52.1cm, head length of 8.58cm, chest length of 28.8cm, shank length of 12.4cm, a back length of 25.35cm, neck circumference 13.98cm, and chest circumference 40.4cm. It can be concluded that local chickens in Kediri have a variety of quantitative characteristics, and the average results for each sub-district are not much different from the others. It is hoped that the results of this study can be used as primary data for further research to determine the quality and superior breeding selection

Antibacterial Activity as Inhibitors Pathogen Bacterial on Pond Shrimp of Extract Marine Biota Collected From Maspari Island, South Sumatera, Indonesia

Marine biota has variety of bioactive compound that is potential to be an antibacterial for shrimp ponds diseases. Some of marine biota has potential as antibacterial i.e. soft coral Sarcophyton sp., Sponge Aaptos sp., seaweeds Sargassum sp. and Halimeda sp. and mangroves Avicennia sp. and Rhizophora sp. species. This study is purposed to find the most potential marine biota as antibacterial. The research method was as follows; sampling, sample identification, extraction and antibacterial activity test. The results is soft coral and sponge extract Sarcophyton sp. has bioactivity against of shrimp bacteria pathogen such as Vibrio spp2. bacteria for around 6.3±0.1 mm, while Aaptos sp. has bioactivity against Vibrio spp1. bacteria for around 7.9+0.1 mm, Vibrio spp2. bacteria for around 7.2± 0.1 to 7.9±0.1 mm, Vibrio spp6. bacteria for around 7.5±0.2 mm, Escherichia coli for around 7.2±0.1 mm and Staphylococcus aureus for around 15.9±0.2 mm. Seaweed extract activity found only of Sargassum sp. which has antibacterial activity against for around 7.1±0.0 mm for Vibrio spp6. and mangrove species activity has Rhizophora sp. extract which has bioactivity against Vibrio spp4. were 7.3±0.1 mm and E. coli bacteria were 6.7±0.1 mm. The most potential marine biota as antibacterial is showed on sponge Aaptos sp.. with an inhibitory zone for around 15.9±0.2 mm (for S. aureus bacteria)
