你們知道台灣海域有很多大白鯊嗎? 🦈 (請向右滑)照片中看到的大白鯊都是在台灣補到的也是世界目前被捕殺到體型最大之一⋯
每年全球有 1 億條鯊魚被獵殺,台灣只有兩千三百萬人口卻被列為全世界四大捕殺地區之一。
我想透過 @empireaqua 來提高人們保護及保存鯊魚的重要性,台灣是一個美麗的島四面環海,周遭有許多很特別的海洋生物,但很少人知道,鯊魚在海洋生態系統中扮演非常重要的角色,少了鯊魚會導致生態系統失衡海洋生物退化,台灣在2020修正「大白鯊象鮫及巨口鯊漁獲管制措施」,這只是一個開始,但還是有非常多的漏洞,每天仍在屠殺大量的鯊魚,我想要此做些事情,這會有非常多的爭議,但我認為透過教育年輕一代需要更加了解海洋生態對地球的影響,這是我們的責任,年輕的一代是未來
Did you know there are a lot of Great White Sharks in Taiwan? Swipe to see some of the biggest recorded great white sharks ever caught by fishing vessels and fishing nets in the world, and these were all in Taiwan. Roughly 100 million sharks are caught and killed a year globally. For only 23 million people on the island, Taiwan is ranked top 4 in the world for the amount of sharks killed per year. This is tragic.
Through Empire Aqua I want to bring more awareness and education on the importance of saving and protecting Sharks in the ocean, in particular Taiwan. Taiwan is a beautiful island and has extraordinary marine life around it, and not many people know this. Sharks are an essential and integral part of the entire marine eco system. Without them, there will be an unbalance and bring degradation to marine life. In 2020 Taiwan passed laws protecting Great White Sharks and a few other rare shark breeds. It’s a good start, but there’s still too many loopholes in these laws, and tons of sharks are still being slaughtered daily. I want to do something about this, and I want to find the right way with the right balance without stepping on too many toes. I know this will be a controversial journey, but I think the younger generation needs to be more aware and needs to be educated on the state of the marine life and how it affects the planet and each one of us. This is our responsibility now and the younger generation is the future.

🔔#你的肝包太多油了嗎❗❗
🎯#脂肪肝 是國人常見的肝臟疾病,早期沒有明顯症狀,長期下來卻可能演變為肝炎、肝硬化或肝癌,迄今仍缺乏有效治療藥物💊。本院生物化學研究所 #陳瑞華 特聘研究員團隊發現一種操控細胞自噬(autophagy)的新機制,✅經動物實驗證明能 #抑制脂肪肝形成。
#什麼是細胞自噬
細胞自噬是細胞的主要資源回收機制,可消除細胞內的老舊廢物,或選擇性地清除細胞內的過多脂肪。
👨🔬👩🔬研究團隊發現一個名為UBE3C的泛素接合酶與一個名為TRABID的去泛素酶,共同調控細胞自噬因子VPS34,以達到細胞內的恆定狀態 👇
1⃣UBE3C藉分枝型泛素化修飾VPS34蛋白質,導致VPS34降解(degradation),被分解為小片段,#抑制 細胞自噬功能。
2⃣TRABID去除VPS34的泛素化修飾,使其不被降解,#促進 細胞自噬。
團隊以高脂飼料餵食小鼠誘發產生脂肪肝後,發現小鼠肝細胞內 #TRABID表現量下降,#無法啟動肝臟細胞的自噬作用。當這些小鼠被注射以腺病毒載體攜帶的TRABID基因,四週後從細胞切片觀察,✅肝臟油脂含量明顯減少,✅能抑制脂肪肝形成。

陳瑞華表示,「🎉本研究對於脂肪肝的治療提供新契機,若能研發出提高TRABID表現或其活性的 #藥物,則可能阻斷脂肪肝的形成,進而預防肝功能異常、肝臟發炎等相關疾病。」
🌏研究成果於本(110)年2月發表在國際期刊《自然通訊》(Nature Communications)。

Fatty liver is a prevalent liver disease in Taiwan and worldwide and is associated with obesity, diabetes and cardiovascular diseases. Although fatty liver is normally asymptomatic, its progression can lead to hepatitis, cirrhosis, and even liver cancer. The research team of Dr. Ruey-Hwa Chen at Institute of Biological Chemistry identifies a novel autophagy regulatory mechanism and a potential of preventing fatty liver progression by manipulating this mechanism. The study has recently been published on February 26 in Nature Communications.

🚩極端天氣帶來的暴風雨間接害死了海豚
一篇看了讓我覺得心裡很不舒服的報導
近年極端天氣帶來的暴雨令海水的鹽度下降
令住在沿海的海豚感染致命性的皮膚病
由2005年起相繼出現死亡個案T^T難過
這都是跟氣候變遷有關
這都是跟我們的生活有關
在這些事上我覺得非常無能為力
沒辦法讓海洋生物有一個好的棲息地
減碳這件事真的很不容易
我們都一起一直的步向滅亡
//The study, published in Scientific Reports, a peer-reviewed natural sciences journal, provides the first-ever case definition for fresh-water skin disease in bottlenose dolphins.
This study comes on the heels of significant outbreaks in Louisiana, Mississippi, Alabama, Florida and Texas and Australia in recent years. In all of these locations, a sudden and drastic decrease in salinity in the waters was the common factor. Coastal dolphins are accustomed to seasonal changes in salinity levels in their marine habitat, but they do not live in freshwater. The increasing severity and frequency of storm events like hurricanes and cyclones, particularly if they are preceded by drought conditions, are dumping unusual volumes of rain that turn coastal waters to freshwater. Freshwater conditions can persist for months, particularly after intense storms such as hurricanes Harvey and Katrina. With the increasing climate temperatures, climate scientists have predicted extreme storms like these will occur more frequently and, consequently, will result in more frequent and severe disease outbreaks in dolphins.
“This devastating skin disease has been killing dolphins since Hurricane Katrina, and we’re pleased to finally define the problem,” said Duignan. “With a record hurricane season in the Gulf of Mexico this year and more intense storm systems worldwide due to climate change, we can absolutely expect to see more of these devastating outbreaks killing dolphins.”
The study has major implications for the current outbreak in Australia, which is impacting the rare and threatened Burrunan dolphin in southeast Australia, and could provide professionals with the information needed to diagnose and treat affected animals. Currently, the long-term outlook for dolphins affected with the skin disease is poor. This is especially true for the animals suffering from prolonged exposure to freshwater.
The deadly skin disease was first noted by researchers on approximately 40 bottlenose dolphins near New Orleans after Hurricane Katrina in 2005.
“As warming ocean temperatures impact marine mammals globally, the findings in this paper will allow better mitigation of the factors that lead disease outbreaks for coastal dolphin communities that are already under threat from habitat loss and degradation,” said Duignan. “This study helps shed light on an ever-growing concern, and we hope it is the first step in mitigating the deadly disease and marshalling the ocean community to further fight climate change.”//
