Ukuhlaziywa Kwemibono Eyisisekelo Yebhayoloji Yamamolekyuli Kumaseli Aphilayo Ibhayoloji yamamolekyuli iyigatsha lebhayoloji elifunda izinqubo zokuphila ezingeni lamamolekyuli, ikakhulukazi indlela ulwazi lwezakhi zofuzo olugcinwa, oluvezwa ngayo, olulawulwa ngayo, noluzuzwa ngayo ngaphakathi kwamaseli. Ngaphakathi kwamaseli aphilayo, amamolekyuli ahlukahlukene—njenge-DNA, i-RNA, amaprotheni, amafutha, nama-carbohydrate—asebenza ndawonye ukwakha inethiwekhi yezinqubo ehlelekile kakhulu. Ukuhlaziywa kwemibono eyisisekelo yebhayoloji yamamolekyuli… Funda kabanzi

Ukubaluleka Kokuqeqeshwa Ocwaningweni Lwezokwelapha Ucwaningo lwezokwelapha ludlala indima ebalulekile ekuthuthukiseni impilo yabantu, kusukela ekutholeni imithi emisha kanye nokuthuthukisa imithi yokugoma kuya ekuqondeni izindlela zezifo ezingeni lama-molecule. Kodwa-ke, ngemuva kwayo yonke incwadi yesayensi kanye nentuthuko yezokwelapha kunenqubo ende edinga ukunemba okuphezulu, ubuqotho besayensi, kanye namakhono obuchwepheshe nawokuhlaziya anele.

I-Biomedicine Ocwaningweni Lwesifo Sikashukela Sohlobo 2 Isifo sikashukela sohlobo 2 (T2DM) singesinye sezifo ezivame kakhulu ze-metabolic emhlabeni jikelele futhi sibeka inselele enkulu ezinhlelweni zokunakekelwa kwempilo. Lesi simo sibonakala ngamazinga aphezulu kashukela egazini ngenxa yokuhlanganiswa kokumelana ne-insulin kanye nokusebenza kabi kwamaseli e-pancreatic beta. Emashumini eminyaka amuva nje, … Funda kabanzi

Indima Yezokwelapha Nge-Bio Ekuthuthukiseni Izindlela Zokwelapha Ezintsha: Intuthuko yokunakekelwa kwempilo emashumini eminyaka amuva nje ayihlukaniseki nomnikelo wesayensi yezokwelapha nge-biomedical. I-Biomedicine iyinkambu yezifundo eziningi ehlanganisa i-biology, imithi, i-chemistry, i-genetics, i-bioinformatics, kanye nobuchwepheshe bobunjiniyela ukuqonda izindlela zezifo nokuklama izixazululo zokwelapha. Emongweni wokuthuthukisa izindlela zokwelapha ezintsha, i-biomedicine idlala indima ebalulekile: kusukela ekutholeni imigomo… Funda kabanzi

I-Biomedicine Ekwelashweni Kwezifo Zezinso Isifo sezinso siyinkinga yezempilo ekhulayo emhlabeni wonke, ethinta kokubili izinhlobo ezibukhali nezingamahlalakhona. Lapho ukusebenza kwezinso kwehla, umzimba uyazabalaza ukuhlunga imfucuza ye-metabolic, ukugcina ibhalansi yoketshezi kanye ne-electrolyte, nokulawula umfutho wegazi kanye nokukhiqizwa kwama-hormone athile. Emashumini eminyaka amuva nje, intuthuko kwezokwelapha nge-biomedicine—inhlanganisela yezokwelapha, i-biology, ubunjiniyela, kanye... Funda kabanzi

Ukubaluleka Kwezincwadi Ocwaningweni Lwezokwelapha Ezweni elishintsha ngokushesha locwaningo lwezokwelapha, izincwadi zesayensi zidlala indima ebalulekile. Akuyona nje umthombo wolwazi kodwa futhi iyisisekelo sabacwaningi sokuklama imibuzo efanele yocwaningo, bakhethe izindlela ezifanele, futhi bahumushe imiphumela ngokuzibophezela. Ngaphandle kokuqonda okuqinile kwezincwadi, ucwaningo lusengozini yokuphinda... Funda kabanzi

Ukusetshenziswa Kwezokwelapha Kwezobuchwepheshe Be-Drone Ubuchwepheshe be-drone (imoto yasemoyeni engenamuntu—i-UAV) abusagcini nje ngezidingo zempi, izithombe, noma imephu. Eminyakeni eyishumi edlule, ama-drone aphenduke amathuluzi anethonya elikhulu kwezempilo kanye nezinsizakalo zezokwelapha. Njengoba enekhono lokundiza ngokushesha, afinyelele ezindaweni ezinzima, athwale umthwalo othile, futhi axhumeke ezinhlelweni zedijithali, ama-drone aqala... Funda kabanzi

I-Biomedicine Ocwaningweni Lwezempilo Yabesifazane Ucwaningo lwezokwelapha ludlala indima ebalulekile ekuqondeni, ekuvimbeleni, nasekwelapheni izinkinga ezahlukahlukene zezempilo eziqondene nabesifazane futhi ezibhekene nabo kakhulu. Impilo yabesifazane ayihlanganisi nje kuphela uhlelo lokuzala kodwa futhi nezimo zenhliziyo, i-metabolic, i-autoimmune, impilo yengqondo, kanye nokuguga. Emashumini eminyaka amuva nje, izindlela zezokwelapha ziye zathuthuka ngokushesha ngenxa yentuthuko yebhayoloji… Funda kabanzi

Ukubaluleka Kokugcinwa Kwemfihlo Yedatha Ku-Biomedicine Ukuthuthukiswa okusheshayo kwe-biomedicine—kusukela kumarekhodi ezokwelapha e-elekthronikhi, izivivinyo zemitholampilo, ama-biobank, kuya ekuhlaziyweni kwe-genomic okusekelwe kubuhlakani bokwenziwa—kulethe izinzuzo ezibalulekile empilweni yomphakathi. Kodwa-ke, le ntuthuko iphinde iveze inselele enkulu: indlela yokugcina imfihlo yedatha yesiguli kanye nesihloko socwaningo. Ukugcinwa kwemfihlo yedatha ku-biomedicine akuyona nje indaba yobuchwepheshe, kodwa kuyisimiso sokuziphatha kanye… Funda kabanzi

Ubuchwepheshe bezokwelapha ocwaningweni lwe-HIV Ucwaningo lwe-HIV luye lwathuthuka kakhulu selokhu kwatholakala igciwane okokuqala ekuqaleni kwawo-1980. Ngemuva kwalokhu kuthuthuka, ubuchwepheshe bezokwelapha budlala indima ebalulekile—kusukela ekuxilongweni okusheshayo nokunembile ngokwengeziwe kanye nokumakwa kwezakhi zofuzo zegciwane kuya ekuthuthukisweni kwemithi yokwelapha i-antiretroviral (ARV) esebenza kahle kakhulu. Namuhla, ubuchwepheshe bezokwelapha abugcini nje ngokusiza… Funda kabanzi
