Levant Drought Occurrence, Lebanon Case

引用

Atmospheric and Climate Sciences 2024年第1期14卷 118-127页

作者： Ihab Jomaa Mariam Choker Nisrine El Haj Marie Therese Abi Saab Matteo Funaro Simone Mereu Department of Irrigation and AgroMeteorology (DIAM) of the Lebanese Agriculture Research Institute (LARI) Tal Amara Lebanon Climate and Water Unit Lebanese Agricultural Research Institute Fanar Lebanon CMCC—Centro Euro-Mediterraneo sui Cambiamenti Climatici IAFES Division Sassari Italy

Rainfall data is probably one of the longest-recorded climatic parameters in Lebanon. On the central coast of Lebanon, the Beirut weather station started collecting rainfall data in 1876. However, the recorded data is not available at one data provider source. Published data is found in historical documents but it reaches the early 1970s and then appears a data gap till 1990. Still the data is available, but it might be found to be saved privately. This study investigated the SPI variability on annual time scale between the years 1876 and 2021. The SPI was computed using R-Stat software to compare every year between 1876 and 2021. The majority (about 70% of the years) of the years are near normal in the precipitation rate. The Standardized Precipitation Index (SPI) demonstrated a normal distribution of years. Dry and wet years constitute about 15% of the total 146 years (1876-2021). Extremely dry years might appear in two consecutive years between 50 to 60 years count. After 1991, there were no wet years it was only near normal and few dry years. The last 30 years showed a trend of increasing drought years without any occurrence of wet years. This study demonstrated the importance of keeping records of at least rainfall data and it must be recorded on a daily basis or intensity on time. It is highly important on a managerial basis and for water security reasons to understand the drought event occurrence and investigate the changes in rainfall rates. Climate change scenarios always forecast a decrease in rainfall rates which will not appear without such studies.

Nitrogen cycling and environmental impacts in upland agricultural soils in North China： A review

引用

Journal of Integrative Agriculture 2017年第12期16卷 2848-2862页

作者： JU Xiao-tang ZHANG Chong College of Resources and En vironmen tal Sciences China Agricultural University Beijing 100193 P.R. China

The upland agricultural soils in North China are distributed north of a line between the Kunlun Mountains, the Qinling Mountains and the Huaihe River. They occur in arid, semi-arid and semi-humid regions and crop production often depends on rain-fed or irrigation to supplement rainfall. This paper summarizes the characteristics of gross nitrogen（N） transformation, the fate of N fertilizer and soil N as well as the N loss pathway, and makes suggestions for proper N management in the region. The soils of the region are characterized by strong N mineralization and nitrification, and weak immobilization and denitrification ability, which lead to the production and accumulation of nitrate in the soil profile. Large amounts of accumulated nitrate have been observed in the vadose-zone in soils due to excess N fertilization in the past three decades, and this nitrate is subject to occasional leaching which leads to groundwater nitrate contamination. Under farmer＇s conventional high N fertilization practice in the winter wheat-summer maize rotation system（N application rate was approximately 600 kg ha–1 yr–1）, crop N uptake, soil residual N, NH_3 volatilization, NO_3~– leaching, and denitrification loss accounted for around 27, 30, 23, 18 and 2% of the applied fertilizer N, respectively. NH_3 volatilization and NO_3~– leaching were the most important N loss pathways while soil residual N was an important fate of N fertilizer for replenishing soil N depletion from crop production. The upland agricultural soils in North China are a large source of N_2O and total emissions in this region make up a large proportion（approximately 54%） of Chinese cropland N_2O emissions. The “non-coupled strong ammonia oxidation” process is an important mechanism of N_2O production. Slowing down ammonia oxidation after ammonium-N fertilizer or urea application and avoiding transient high soil NH4＋ concentrations are key measures for reducing N_2O emissions in this region. Further N management shou

LARYNGEAL RECONSTRUCTION AND SURVIVAL AFTER FUNCTION-SPARING LARYNGECTOMY FOR SELECTED T3 AND T4 LESIONS

引用

中华医学杂志(英文版) 1995年第6期 25-29页

Most patients lost their vocal ability after ablative surgery for the laryngeal cancer. Total laryngectomy has a history of over 100 years, hence many surgeons are accustomed to the en bloc organ resection and the loss of ability for communication after surgery. The recent advance of surgery introduces the concept and technique of radical cure and functional preservation of the cancer-afflicted-organ at same setting. For lesions of late T categories (T3, T4), the maintenance of normal function after wide resection to ensure radicality demands a special technique to repair the crippled larynx. For this purpose a local osteomuscular flap was designed to reconstruct a functioning larynx. The surgical manoeuvre was described and the result proved to be successful. The outcome of 138 patients with T3 and T4 laryngeal carcinomas following conservation laryngectomy was analyzed. The five-year survival rate was 69% for supraglottic type and 75% for glottic type. The quality of life was much improved.

Neuroprotective Autophagic Flux Induced by Hyperbaric Oxygen Preconditioning is Mediated by Cystatin C

引用

Neuroscience Bulletin 2019年第2期35卷 336-346页

作者： Zongping Fang Yun Feng Yuheng Li Jiao Deng Huang Nie Qianzhi Yang Shiquan Wang Hailong Dong Lize Xiong Department of Anesthesiology and Perioperative Medicine Xijing HospitalThe Fourth Military Medical University Department of Gastroenterology The First Affiliated Hospi-tal of Xi'an Jiaotong University

We have previously reported that Cystatin C(CysC) is a pivotal mediator in the neuroprotection induced by hyperbaric oxygen(HBO) preconditioning; however,the underlying mechanism and how CysC changes after stroke are not clear. In the present study, we demonstrated that CysC expression was elevated as early as 3 h after reperfusion, and this was further enhanced by HBO preconditioning. Concurrently, LC3-II and Beclin-1, two positive-markers for autophagy induction, exhibited increases similar to CysC, while knockdown of CysC blocked these elevations. As a marker of autophagy inhibition, p62 was downregulated by HBO preconditioning and this was blocked by CysC knockdown. Besides, the beneficial effects of preserving lysosomal membrane integrity and enhancing autolysosome formation induced by HBO preconditioning were abolished in CysC-/-***, we demonstrated that exogenous CysC reduced the neurological deficits and infarct volume after brain ischemic injury, while 3-methyladenine partially reversed this neuroprotection. In the present study, we showed that CysC is biochemically and morphologically essential for promoting autophagic flux, and highlighted the translational potential of HBO preconditioning and CysC for stroke treatment.
