Bacterial spores can remain dormant for decades, yet harbor the exceptional capacity to rapidly resume metabolic activity and recommence life. SIS17 Although germinants and their corresponding receptors have been known for more than 30 years, the molecular events underlying this remarkable cellular transition from dormancy to full metabolic activity are only partially defined.

Here, we examined whether protein phospho-modifications occur during germination, the first step of exiting dormancy, thereby facilitating spore revival. Utilizing Bacillus subtilis as a model organism, we performed phosphoproteomic analysis to define the Ser/Thr/Tyr phosphoproteome of a reviving spore. The phosphoproteome was found to chiefly comprise newly identified phosphorylation sites located within proteins involved in basic biological functions, such as transcription, translation, carbon metabolism, and spore-specific determinants. Quantitative comparison of dormant and germinating spore phosphoproteomes revealed phosphorylation dynamics, indicating that phospho-modifications could modulate protein activity during this cellular transition. Furthermore, by mutating select phosphorylation sites located within proteins representative of key biological processes, we established a functional connection between phosphorylation and the progression of spore revival.

Herein, we provide, for the first time, a phosphoproteomic view of a germinating bacterial spore. We further show that the spore phosphoproteome is dynamic and present evidence that phosphorylation events play an integral role in facilitating spore revival.

Enabling women living with HIV to effectively plan whether and when to become pregnant is an essential right; effective prevention of unintended pregnancies is also critical to reduce maternal morbidity and mortality as well as vertical transmission of HIV. The objective of this study is to examine the use of family planning (FP) services by HIV-positive and HIV-negative women in Kenya and their ability to achieve their fertility desires.

Data are derived from a random sample of women seeking family planning services in public health facilities in Kenya who had declared their HIV status (1887 at baseline and 1224 at endline) and who participated in a longitudinal study (the INTEGRA Initiative) that measured the benefits/costs of integrating HIV and sexual/reproductive health services in public health facilities. The dependent variables were FP use in the last 12 months and fertility desires (whether a woman wants more children or not). The key independent variable was HIV status (positive and negative). Dlity desires were age, education level and household wealth status.

The findings highlight important gaps related to utilization of FP among WLHIV. Despite having a greater likelihood of reported use of FP, HIV-positive women were more likely to have had an unintended pregnancy compared to HIV-negative women. This calls for need to strengthen family planning services for WLHIV to ensure they have better access to a wide range of FP methods. There is need to encourage the use of long-acting reversible contraceptive (LARC) to reduce the risk of unintended pregnancy and prevention of vertical transmission of HIV. However, such policies should be based on respect for women's right to informed reproductive choice in the context of HIV/AIDS.

We examined variability of speech intelligibility scores and how well intelligibility scores predicted group membership among 5-year-old children with speech motor impairment (SMI) secondary to cerebral palsy and an age-matched group of typically developing (TD) children.

Speech samples varying in length from 1-4 words were elicited from 24 children with cerebral palsy (mean age 60.50 months) and 20 TD children (mean age 60.33 months). Two hundred twenty adult listeners made orthographic transcriptions of speech samples (n = 5 per child).

Variability associated with listeners made a significant contribution to explaining the variance in intelligibility scores for TD and SMI children, but the magnitude was greater for TD children. Intelligibility scores differentiated very well between children who have SMI and TD children when intelligibility was at or below approximately 75% and above approximately 85%.

Intelligibility seems to be a useful clinical tool for differentiating between TD children and children with SMI at 5 years of age; however, there is considerable variability within and between listeners, highlighting the need for more than one listener per child to ensure validity of an intelligibility measure.

To determine three-dimensional (3D) effects of three different rapid maxillary expansion (RME) appliances on facial soft tissues.

Forty-two children (18 boys, 24 girls) who required RME treatment were included in this study. Patients were randomly divided into three equal groups banded RME, acrylic splint RME, and modified acrylic splint RME. For each patient, 3D images were obtained before treatment (T1) and at the end of the 3-month retention (T2) with the 3dMD system.

When three RME appliances were compared in terms of the effects on the facial soft tissues, there were no significant differences among them. The mouth and nasal width showed a significant increase in all groups. Although the effect of the acrylic splint RME appliances on total face height was less than that of the banded RME, there was no significant difference between the appliances. The effect of the modified acrylic splint appliance on the upper lip was significant according to the volumetric measurements (P < .01).

There were no significant differences among three RME appliances on the facial soft tissues. The modified acrylic splint RME produced a more protrusive effect on the upper lip.

The aims of this study were to examine ME1 and ME2 expression in normal skin and sebaceous lesions. A total of 68 cases including 5 specimens of normal skin, 12 facial lesions showing sebaceous hyperplasia, 18 sebaceous adenomas, 10 sebaceomas, 13 steatocystomas, and 10 sebaceous carcinomas were examined for the expression of ME1 and ME2. All benign and malignant sebaceous lesions showed ME1 in clear cells and ME2 in nonclear cells, respectively. ME1/ME2 phenotype is seen in basal sebocytes, basal keratinocytes, sweat glands, and outer root sheath cells and hence not specific. This study demonstrates that ME1/ME2 expression phenotype may have a potential to be a valuable marker for sebaceous differentiation. It is necessary to perform large-scale studies including skin tumors with a clear cell morphology that may mimic sebaceous differentiation.Milia en plaque (MEP) is an uncommon disorder characterized by an erythematous plaque containing numerous milia. The pathogenesis of MEP is not clear. The authors report a man with an erythematous plaque on the right retroauricular area, containing numerous white-yellow cysts varying in size. Histological examination showed that multiple cystic structures at various levels of the dermis that were lined by stratified squamous epithelium and contained keratinous material-these findings were consistent with the diagnosis of multiple milia. In addition to epidermal cysts, however, the lesion consisted of a branched proliferation of pale-staining keratinocytes lined with basal keratinocytes budding from the overlying epidermis. Moreover, some cysts were formed within the branched epithelial proliferation, had thicker cyst walls than the ordinary milium, or had irregular or branched projections toward the surrounding dermis. From these findings, the authors conclude that MEP is a distinct follicular hamartoma with cystic trichoepitheliomatous features.Surprisingly efficient solid-state electron transport has recently been demonstrated through "dry" proteins (with only structural, tightly bound H2O left), suggesting proteins as promising candidates for molecular (bio)electronics. Using inelastic electron tunneling spectroscopy (IETS), we explored electron-phonon interaction in metal/protein/metal junctions, to help understand solid-state electronic transport across the redox protein azurin. To that end an oriented azurin monolayer on Au is contacted by soft Au electrodes. Characteristic vibrational modes of amide and amino acid side groups as well as of the azurin-electrode contact were observed, revealing the azurin native conformation in the junction and the critical role of side groups in the charge transport. The lack of abrupt changes in the conductance and the line shape of IETS point to far off-resonance tunneling as the dominant transport mechanism across azurin, in line with previously reported (and herein confirmed) azurin junctions. The inelastic current and hence electron-phonon interaction appear to be rather weak and comparable in magnitude with the inelastic fraction of tunneling current via alkyl chains, which may reflect the known structural rigidity of azurin.Currently, bisadducts of C60 and C70 fullerenes are widely studied as electron-acceptor materials for organic solar cells. These compounds are usually used as mixtures of the positional isomers. However, as recently shown, the separate use of the purified isomers with lowest anisotropies of polarizability may enhance solar cell output parameters. To predict the structures of the compounds appropriate for this purpose, we calculated anisotropies of polarizability of four classes of fullerene bisadducts, namely, bis-[60]PCBM, [60]OQMF, bis-[70]PCBM, and [70]OQMF (18, 16, 41, and 42 positional isomers, respectively). As found, the anisotropies quadratically correlate with the interaddend distances in fullerene bisadducts, whereas there are no obvious correlations between the structures and lowest unoccupied molecular orbital levels, traditionally used for assessing the efficiency of candidates for organic solar cell electron acceptors. According to our calculations, bisadducts bis-[60]PCBM-ee-1, [60]OQMF-cis-3.2, [60]OQMF-trans-4.2, cc(1.1)cc(2'.1)-bis-[70]PCBM, and cc1cc(2'.1)-[70]OQMF have the lowest anisotropies of polarizability. These compounds have a primary interest for synthesis, purification, and further separate testing in solar cells. The structures of these adducts have a common feature, which we describe with the "not so close and not so far" rule the distances between the addends in the most isotropic fullerene bisaddicts should be medium among the possible values. These are ee, ef, cis-3, and trans-4 positions in the case of the C60 bisadducts and cc bonds placed on the different poles and the same hemisphere of the C70 skeleton.
