Izimiso Eziyisisekelo Zokuhlolwa Kokuncibilikiswa Kwethebhulethi: Ukuhlolwa kokuncibilikiswa kwethebhulethi kuwukuhlolwa okubalulekile kokulawula ikhwalithi ekuthuthukisweni, ekukhiqizweni, nasekulawulweni kwekhwalithi yezinhlobo zomthamo eziqinile zomlomo. Kalula nje, ukuncibilikiswa inqubo lapho isithako esisebenzayo efomini yomthamo (isb., ithebhulethi) sincibilika khona sibe yindawo yoketshezi ngaphansi kwezimo ezithile. Nakuba kubonakala kulula, lokhu kuhlolwa kudlala indima ebalulekile ngoba… Funda kabanzi

Izimpawu Zama-Molecular ku-Pharmacogenomics I-Pharmacogenomics yinkambu yesayensi ehlola ukuthi ukushintshashintsha kwezakhi zofuzo zomuntu kuthinta kanjani impendulo yakhe emithini, kokubili ngokusebenza kahle kanye nengozi yemiphumela emibi. Umgomo wayo wokugcina ukufeza umuthi onembile—okungukuthi, ukukhetha uhlobo lomuthi olufanele kakhulu kanye nomthamo womuntu ngamunye. Empeleni, i-pharmacogenomics incike ezimpawini zama-molecular, okungukuthi ukuhlukahluka... Funda kabanzi

Umphumela Wokukhanya Ekuzinzeni Kwemithi Ukuzinza kwemithi yikhono lomuthi wokwelapha lokugcina ikhwalithi yawo, ukuphepha, kanye nokusebenza kahle ngesikhathi sokugcina nokusebenzisa. Phakathi kwezinto ezahlukahlukene ezithinta ukuzinza—njengokushisa, umswakama, umoya-mpilo, kanye ne-pH—ukukhanya kuyimbangela enkulu yokuwohloka kwemithi, ikakhulukazi emithini ezwela imisebe. Ukuchayeka ekukhanyeni kungabangela ukusabela… Funda kabanzi

Izakhiwo Ze-Physicochemical Zezinto Zemithi Ekuthuthukisweni kwemithi yanamuhla, impumelelo ye-molecule ekubeni umkhiqizo wokwelapha ophumelelayo ayinqunywa nje kuphela ngomsebenzi wayo wezokwelapha kodwa futhi nezakhiwo zayo ze-physicochemical. Izakhiwo ze-physicochemical zihlanganisa izici ezihlobene nesakhiwo sama-molecule, isimo somzimba, ukusebenzisana nezinyibilikisi, kanye nokuqina ngaphansi kwezimo ezahlukahlukene zemvelo. Ukuqonda okuphelele kwalezi zici… Funda kabanzi

Ukumelana nama-antibiotic kanye nomthelela wawo Ukumelana nama-antibiotic kungenye yezinselelo ezinkulu zezempilo emhlabeni wonke zaleli khulu leminyaka. Lesi simo senzeka lapho amabhaktheriya eshintsha ngendlela yokuthi ama-antibiotic—imithi okufanele ibulale noma ivimbele ukukhula kwawo—angasebenzi kahle. Ngenxa yalokho, izifo ezazilula ukuzelapha ngaphambili zingaba nzima ukuzelapha, zihlale isikhathi eside, futhi zize zandise nengozi yezinkinga kanye... Funda kabanzi

Umehluko Phakathi Kwama-Serum Nemithi Yokugoma: Ukuqonda Lezi Zindlela Ezimbili Ezibalulekile Zezokwelapha Impilo yabantu iye yathuthuka kakhulu phakathi namakhulu eminyaka, ngenxa yokutholakala nokuthuthukiswa kwezindlela ezahlukene zezokwelapha. Phakathi kwezindlela zezokwelapha ezinethonya elikhulu kukhona ama-serum nemithi yokugoma. Nakuba kokubili kuvame ukuhlotshaniswa nokuvimbela nokwelapha izifo, ama-serum nemithi yokugoma empeleni kunomehluko oyisisekelo ngesimo, umsebenzi, kanye... Funda kabanzi

Ukuhlinzekwa Kwemithi Ephuthumayo: Ukulungela, Izinselele, kanye Nezixazululo Impilo ivame ukuveza ukungaqiniseki kwayo ngezimo eziphuthumayo ezingalindelekile, njengezinhlekelele zemvelo, ukuqubuka kwezifo, noma izingozi ezinkulu, okungadala isidingo esiphuthumayo semithi. Ukuhlinzekwa kwemithi ephuthumayo kuyisici esibalulekile ekuqinisekiseni impilo yomphakathi nokuphepha. Lesi sihloko sizoxoxa ngokubaluleka… Funda kabanzi

Ukuphathwa Kwemfucuza Yemboni Yezemithi Imboni yezemithi idlala indima ebalulekile ekuhlangabezaneni nezidingo zezempilo zomphakathi. Kodwa-ke, le mboni ikhiqiza nemfucuza, uma ingaphathwa kahle, engathinta kabi imvelo kanye nempilo yabantu. Imfucuza yemboni yezemithi iqukethe izinhlobo ezahlukene zamakhemikhali, izinto eziphilayo, kanye nezinto ezingaphili ezingangcolisa amanzi, inhlabathi, nomoya. Ngu… Funda kabanzi

Ukuthuthukiswa Kwemithi Yokulwa Negciwane: Isikhathi Esisha Ekulweni Namagciwane Kulesi sikhathi sanamuhla, intuthuko kwezesayensi yezokwelapha ivule ithuba elisha lokutholakala nokuthuthukiswa kwemithi yokulwa namagciwane, ebalulekile ekulweni nokutheleleka kwamagciwane okuqhubeka kuvela. Amagciwane ayizinto eziphilayo ezibangela izifo ezinezinga eliphezulu lokuguquka, okufaka inselelo ikhono lososayensi emhlabeni wonke lokuthola... Funda kabanzi

Umphumela we-Ethanol Ekwakheni Kwemithi I-Ethanol iyikhemikhali evame ukusetshenziswa ekwakhekeni kwemithi ehlukahlukene. Ukuba khona kwayo ekwakhekeni kunemisebenzi eyahlukahlukene futhi kuthinta kakhulu impumelelo yomkhiqizo ophumayo. Lesi sihloko sizohlola ithonya le-ethanol ekwakhekeni kwemithi ngokujulile, simboze indima yayo, izinzuzo, kanye nezingozi ezingaba khona. Isingeniso… Funda kabanzi
