MMP-9 overexpression is associated with a poor outcome in MDR-TB patients, indicating that MMP-9 is a suitable target for MDR-TB therapy. MMP-9 also includes SNPs that occur at inhibitor binding areas as well as zinc ions. As a result of polymorphisms, the usage of MMP-9 inhibitors for MDR-TB might vary. Through molecular simulation, it has been found that the mutant MMP-9 has a larger cavity and a more lipophilic surface. The docking tests revealed that EGTA had the least amount of binding energy to both wild-type and mutant MMP-9. The wildtype MMP-9 can bind zinc when EGTA is in the active site. This shows that using EGTA to chelate Zn is only partially successful. However, the binding energy of EGTA at the active site suggests that it may be a competitor to MMP-9 substrates. On the other hand, Zn is not involved in the interaction of the mutant MMP-9-EGTA complex.
Tuberkulosis (TB) merupakan salah sat masalah kesehatan di republic Indonesia. Indonesia menempati urutan kedua setelah India untutk kasus TB dengan kematian 100,000 kaus di tahun 2015.Penyebab tersering kematian Tb adalah perkembangan dan pengobatan TB yang tidak adekuat sehingga menyebabkan komplikasi seperti TB luluh paru. Perburukan kondisi pasien TB disebabkan oleh buruknya status nutrisi (malnutrisi) yang dapat dinilai melalui kadar serum albumin.Tujuan penelitian ini adalah untuk mengetahui hubungan antara hipoalbuminemia dengan kejadian TB luluh paru. Desain penelitian adalah analitik observasi dengan pendekatan case control. Diman subjek peneltian berjumlah 60 orang yang dibagi menjadi 30 orang kelompok kontrol (TB Paru) dan 30 orang lainnya kelompok kasus (TB luluh Paru). Pengukuran kadar albumin dilakukan pada bulan Februari hingga Maret 2017. Analisa statistik menggunakan uji chi square.Distribusi frekuensi TB luluh paru berdasarkan usia didapatkan usia 18-55 tahun sebanyak 17 orang (56,7%), berdasarkan jenis kelamin didapatkan lebih banyak pasien laki-laki sebanyak 21 orang (70%), berdasarkan kadar albumin didapatkan sebanyak 20 orang mengalami hipoalbumnemia (66,7%). Hasil uji korelasi menunjukkan nilai p = 0,002 (OR = 5,5 r= 0,372).Terdapat hubungan bermakna antara Hipoalbuminemia dengan Kejadia TB Luluh Paru.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
