Anti-apoptotic proteins, including Bcl-2 and Bcl-xL, hinder cancer treatment, and several drugs targeting these molecules have been developed. One is ABT-263 (navitoclax), which targets Bcl-2, Bcl-xL, and Bcl-w. On the other hand, hydroxychloroquine (HCQ) has been used as a drug for malaria infection and autoimmune disease. HCQ can exert a similar effect as chloroquine with fewer adverse events. In addition, HCQ exerts antitumor activity. In the present study, the effects of HCQ on ABT-263-induced antitumor activities were examined using three human pancreatic cancer cell lines (PANC-1, MiaPaCa-2, and BxPC-3).In vitro effects of HCQ and ABT-263 were examined by cell viability, colony-forming assays, and flow cytometry. Protein expression was determined by immunoblotting. In vivo effects of HCQ and ABT-263 were examined by a xenograft mice model.Combined treatment with HCQ and ABT-263 synergistically decreased the viability of only BxPC-3 cells. This synergistic effect was not observed when HCQ was combined with ABT-199, an inhibitor specific to Bcl-2. The combination of HCQ and ABT-263 induced caspase-dependent apoptosis. Protein expression of Bcl-xL was more highly expressed in BxPC-3 cells than in the other two cell lines, and the combination of HCQ with a Bcl-xL inhibitor or siRNA-mediated knockdown of Bcl-xL induced apoptosis in BxPC-3 cells. Combination therapy with HCQ and ABT 737, an ABT-263 analogue, suppressed the in vivo growth of BxPC-3 with transient body-weight loss.HCQ effectively promotes Bcl-xL inhibition-induced apoptosis in BxPC-3 human pancreatic cancer cells.

Inhibition of CDK4/6 slows the cell cycle and induces senescence in breast cancer cells. However, senescent cancer cells promote invasion and metastasis. Several drugs reportedly target senescent cells, including ABT‐263 (navitoclax). We examined the effects of the CDK4/6 inhibitor abemaciclib and ABT‐263 on two human breast cancer cell lines. The abemaciclib and ABT‐263 combination additively decreased the viability of MDA‐MB‐231 cells, but not MCF‐7 cells. Also, the combination therapy‐induced caspase‐dependent apoptosis in MDA‐MB‐231 cells. Combination therapy with abemaciclib and ABT‐737, an ABT‐263 analog, significantly suppressed the in vivo growth of MDA‐MB‐231 with transient body‐weight loss. Given that p16Ink4a and p21Cip1/Waf1 are key factors in senescence and that both cell lines were negative for p16, the role of p21 in apoptosis of treated breast cancer cells was investigated. Although abemaciclib increased the cytoplasmic p21 level in both cell lines as a hallmark of senescence, the abemaciclib and ABT‐263 combination decreased it only in MDA‐MB‐231 cells. This decrease of p21 expression was relieved by caspase inhibition, and p21 was colocalized with caspase‐3 in the cytoplasm of MDA‐MB‐231 cells. Alternatively, small interfering RNA‐mediated knockdown of p21 rendered caspase‐3‐negative MCF‐7 cells susceptible to abemaciclib and ABT‐263, as well as TNF‐related apoptosis‐inducing ligand. Furthermore, a clinical database analysis showed that p21high breast cancer patients had a poorer prognosis compared to p21low patients. These results suggest that cytoplasmic p21 plays a protective role in apoptosis of CDK4/6 inhibitor‐induced senescent breast cancer cells., Colocalization of p21 and caspase‐3 in treated MDA‐MB‐231 breast cancer cells.

Stunting merupakan hambatan pertumbuhan yang diakibatkan kekurangan asupan zat gizi juga adanya masalah kesehatan yang berdampak pada perkembangan anak dari tahap awal yaitu saat konsepsi sampai tahun ke 3 atau ke 4 kehidupan anak, dimana keadaan gizi ibu dan anak merupakan faktor penting dari pertumbuhan anak. Stunting pada usia dini berhubungan dengan terjadinya gangguan tingkat kecerdasan anak, perkembangan psikomotorik dan kemampuan motorik halus. Stunting dipengaruhi oleh pendapatan keluarga, pengetahuan gizi ibu, pola asuh ibu, riwayat infeksi penyakit, riwayat imunisasi, asupan protein, dan asupan ibu. Asupan ibu terutama saat hamil merupakan salah satu faktor yang berperan penting. Gizi janin bergantung sepenuhnya pada ibu, sehingga kecukupan gizi ibu sangat memengaruhi kondisi janin yang dikandungnya. Ibu hamil yang kurang gizi akan menyebabkan gangguan pertumbuhan janin dalam kandungan. Dilakukan kegiatan penyuluhan, pengukuran antropometri dan pembagian leaflet mengenai pentingnya asupan nutrisi selama kehamilan dalam mencegah risiko terjadinya stunting pada anak. Kegiatan ini dihadiri 40 orang ibu hamil umur kehamilan trimester I, II dan III. Selama kegiatan kami tetap melakukan protokol kesehatan. Dari hasil pengukuran antropometri didapatkan 6 orang ibu hamil pada trimester III,24 orang trimester II dan 7 orang dengan status gizi baik pada trimester 1. Sedangkan status gizi kurang didapatkan 1 orang ibu hamil pada trimester I dan 2 orang trimester II. Kesimpulan : Dalam mencegah risiko terjadinya stunting pada anak, perlu pemberian nutrisi yang tepat pada ibu hamil sejak di trimester pertama agar tidak terjadinya risiko malnutrisi yang akan berdampak pada anak nantinya

Latar belakang: Terjadi kasus inkompatibilitas karena pemberian darah yang inkompatibel dapat disebabkan oleh dua hal, yang pertama akibat ketidakcocokan golongan darah saat melakukan transfusi sehingga terjadi reaksi hemolisis intravaskular akut dan juga dapat disebabkan oleh reaksi imunitas antara antigen dan antibodi karena adanya golongan darah lain atau antibodi ireguler. Penelitian ini bertujuan untuk menganalisis antibodi ireguler pada hasil inkompatibilitas darah transfusi uji silang serasi darah transfusi. Metode: Penelitian ini merupakan penelitian observasional dengan menggunakan metode cross sectional. Sampel penelitian sebanyak 70 sampel inkompatibel uji silang serasi yang ditemukan di Unit Bank Darah RSUP Dr. Wahidin Sudirohusodo Makassar dan Unit Donor Darah PMI Makassar. Dilakukan pemeriksaan golongan darah dan uji silang serasi jika sampel yang telah di lakukan uji silang serasi dan hasilnya terjadi reaksi inkompatibel golongan darah maka sampel tersebut diambil kemudian di lanjutkan ke Direct antiglobulin test. Sampel yang Direct antiglobulin test positif dilanjutkan dengan pemeriksaan monospesifik yaitu tes IgG dan C3d. Analisis data menggunakan Metode analitik, yaitu dengan uji Chi Square untuk menilai variabel yang berhubungan dengan antibodi ireguler. Hasil: Penelitian menunjukkan bahwa, dari 70 sampel yang mengalami reaksi inkompatibilitas ternyata hanya 7 sampel yang positif memiliki antibodi ireguler, di antaranya Anti E 3 (4,29%), anti CDEd 1 (1,42%), dari ketujuh sampel yang positif terdapat 2 (2,86%) sampel yang positif semua pada sebelas sel panel tersebut dan terdapat 1 (1,42%) sampel yang positif pada sel panel kecil (sel 1 dan sel 2) untuk skrining antibodi. Kesimpulan: Kejadian inkompatibel golongan darah sebagian besar bukan karena adanya antibodi ireguler, hanya sekitar 10% inkompatibel akibat antibodi ireguler terjadi maka skrining antibodi ireguler belum menjadi urgensi di setiap Unit pelayanan Transfusi darah maupun di unit Bank darah Rumah sakit.

Senescence is a state of growth arrest induced not only in normal cells but also in cancer cells by aging or stress, which triggers DNA damage. Despite growth suppression, senescent cancer cells promote tumor formation and recurrence by producing cytokines and growth factors; this state is designated as the senescence‐associated secretory phenotype. In this study, we examined the susceptibility of senescent human breast cancer cells to immune cell‐mediated cytotoxicity. Doxorubicin (DXR) treatment induced senescence in 2 human breast cancer cell lines, MDA‐MB‐231 and BT‐549, with the induction of γH2AX expression and increased expression of p21 or p16. Treatment with DXR also induced the expression of senescence‐associated β‐galactosidase and promoted the production of pro‐inflammatory cytokines. Importantly, DXR‐treated senescent MDA‐MB‐231 cells showed increased sensitivity to 2 types of immune cell‐mediated cytotoxicity: cytotoxicity of activated CD4+ T cells and Ab‐dependent cellular cytotoxicity by natural killer cells. This increased sensitivity to cytotoxicity was partially dependent on tumor necrosis factor‐related apoptosis‐inducing ligand and perforin, respectively. This increased sensitivity was not observed following treatment with the senescence‐inducing cyclin‐dependent kinase‐4/6 inhibitor, abemaciclib. In addition, treatment with DXR, but not abemaciclib, decreased the expression of antiapoptotic proteins in cancer cells. These results indicated that DXR and abemaciclib induced senescence in breast cancer cells, but that they differed in their sensitivity to immune cell‐mediated cytotoxicity. These findings could provide an indication for combining anticancer immunotherapy with chemotherapeutic drugs or molecular targeting drugs.

Blood donation is a process of taking blood from someone, either voluntarily or as a replacement donor blood banked for later usein blood transfusions. Regular donors are donors who regularly donate blood between 3−4 times a year. Nonregular donors are thosewho do not routinely donate blood in a year. Each donor donating one bag of blood, suffered a loss of approximately 200 mg of iron.The purpose of this study was to know the differences in the levels of iron profiles in regular and nonregular donors. The study wasconducted cross sectional on 65 samples of blood from the UPTD Transfusi Darah South Sulawesi Provincial Health Office, consisting of34 regular donors and 31 nonregular donors. Serum iron and TIBC levels were examined using ABX Pentra 400 with colorimetric andimmunoturbidimetry method. Ferritin level was examined using Elecsys with ECLIA principle. The data were then analyzed by unpairedT test. In this study, the regular donors showed an average serum iron level of 87.09 μg/dL, TIBC level 255.41 μg/dL and ferritin level121.27 μg/dL. The nonregular donors, showed an average serum iron level of 83.26 μg/dL, TIBC level was 261.80 μg/dL and ferritinlevel was 158.62 μg/dL. The results showed no significant differences between the levels of iron profiles in regular and nonregulardonors. Based on this study, it can be concluded that regular and nonregular blood donation did not affect the levels of iron profiles. Itis recommended to conduct a further cohort research to know the levels of iron profiles in blood donors by comparing before and afterdonating blood.
