Intimate Technologies of Family Making: Birth Control Politics in Cold War Turkey.

In April 1965, the Turkish Parliament passed the law legalizing birth control, including the pills and the use of intrauterine devices. This article examines the beginnings and expansion of family planning in Turkey in the 1960s by tracing the encounters of American experts, Turkish physicians along with bureaucrats, and thousands of urban squatter dwelling and rural women and men. Different from the previous historical accounts framing family planning as an insular and state-driven modernization project, it provides a transnational history of family planning in Turkey by unearthing intimate links between the discourses of development and histories of family, sexuality, and reproduction.

Bone marrow-derived mesenchymal stem cells alleviate paclitaxel-induced mechanical allodynia in rats.

Anticancer drug paclitaxel (PTX) frequently causes painful peripheral neuropathy; however, no medication has been shown to be effective in the treatment of this debilitating side effect. We aimed to investigate the efficacy of two different doses of allogeneic bone marrow-derived mesenchymal stem cells (BM-MSCs) on PTX-induced mechanical allodynia and spinal cytokine levels and their localization to target tissues such as the spinal cord and sciatic nerve. After the development of mechanical allodynia with repeated PTX administration, two different doses of rat BM-MSCs, low or high (1 × 10 -5 × 10 ), were transplanted into rats and the evaluation continued for 30 days.

Opposite Carcinogenic Effects of Circadian Clock Gene BMAL1.

The circadian clock confers daily rhythmicity on many biochemical and physiological functions and its disruption is associated with increased risks of developing obesity, diabetes, heart disease and cancer. Although, there are studies on the role of Bmal1 in carcinogenesis using germline, conditional or tissue-specific knockouts, it is still not well understood how BMAL1 gene affects cancer-related biological events at the molecular level. We, therefore, took an in vitro approach to understand the contribution of BMAL1 in this molecular mechanism using human breast epithelial cell lines by knocking out BMAL1 gene with CRISPR technology.

Multiple ATR-Chk1 pathway proteins preferentially associate with checkpoint-inducing DNA substrates.

The ATR-Chk1 DNA damage checkpoint pathway is a critical regulator of the cellular response to DNA damage and replication stress in human cells. The variety of environmental, chemotherapeutic, and carcinogenic agents that activate this signal transduction pathway do so primarily through the formation of bulky adducts in DNA and subsequent effects on DNA replication fork progression. Because there are many protein-protein and protein-DNA interactions proposed to be involved in activation and/or maintenance of ATR-Chk1 signaling in vivo, we systematically analyzed the association of a number of ATR-Chk1 pathway proteins with relevant checkpoint-inducing DNA structures in vitro.

Tipin-replication protein A interaction mediates Chk1 phosphorylation by ATR in response to genotoxic stress.

Mammalian Timeless is a multifunctional protein that performs essential roles in the circadian clock, chromosome cohesion, DNA replication fork protection, and DNA replication/DNA damage checkpoint pathways. The human Timeless exists in a tight complex with a smaller protein called Tipin (Timeless-interacting protein). Here we investigated the mechanism by which the Timeless-Tipin complex functions as a mediator in the ATR-Chk1 DNA damage checkpoint pathway.

AgNOR increase in buccal epithelial cells of trisomy 21 infants.

The aim of this study is to compare the Argilophilic Nucleolus Organizer Regions (AgNORs) level between Down syndrome (DS) patients and controls in a tissue sharing the same embryonic origin with the central nervous system and compare the results with those obtained recently by us from DS's lymphocytes. For this, buccal desquamating epithelial cells well known as the ectodermic origin were used. Since the AgNOR staining intensity is an indicator of the ribosomes biosynthesis rate, comparison of the image analysis values of the AgNOR area/total nuclear area (NORa/TNa) in buccal desquamating epithelial cells of DS patients and controls provided a plausible conclusion about the regulation/deregulation of the rRNA genes (rDNA) in these cells of DS babies/infants.
