Human milk is generally considered to be insufficient in vitamin D. However, research completed in the 1980s showed that the vitamin D content of human milk is directly related to maternal serum vitamin D levels and therefore may potentially be adequate if the mother’s vitamin D levels are sufficient. Approximately one-third of the adult population, which includes breastfeeding women, in the United States have vitamin D insufficiency or deficiency. Among infants, 90.4% of breastfed infants are vitamin D deficient compared to 15.4% of formula fed infants. The American Academy of Pediatrics (AAP) has therefore recommended all breastfed infants be directly supplemented with 400 IU per day of vitamin D to decrease the risk of vitamin D insufficiency and rickets. According to the AAP, compliance rates with this recommendation ranges between 2% - 36%. Because the recommendation to supplement may undermine breastfeeding, many pediatricians do not inform their patients of the need to supplement. Additionally, some parents are concerned about directly supplementing their infant as risks may include allergic reactions to the ingredients, aspiration pneumonia, accidental overdose, and changes in intestinal flora and pH which may compromise the immune benefits of human milk. A literature review was conducted to examine the effect of maternal supplementation with vitamin D during lactation on human milk vitamin D content and maternal and infant serum vitamin D levels. Although there is no current consensus regarding dosage and timing of maternal vitamin D supplementation, the literature suggests that high-dose vitamin D supplementation of the lactating mother is as effective at maintaining infant vitamin D levels as direct infant supplementation, while also correcting the mother’s vitamin D deficiency.

基于微扰理论,研究了内部存在一个同轴圆柱扰动体时圆柱谐振腔共振频率的偏移问题.其中,圆柱谐振腔的边侧面是刚性的,上下底面应力自由.经过推导,得出了圆柱扰动体存在时谐振腔的声势与共振频率的表达式.在此基础上,分析了谐振腔与圆柱扰动体各种参数对谐振腔共振频率的影响.数值模拟结果表明,谐振腔的共振频率受扰动体在谐振腔中的位置影响较大.圆柱谐振腔的共振频率在圆柱扰动体居中时是最大值,并且其共振频率对扰动体的声速敏感;当扰动体在谐振腔两端时,谐振腔共振频率是最小值,并且其对扰动体的密度敏感.最后,通过数值模拟结果和实验测量结果之间的对比,发现两者的基本变化趋势是吻合的.

Xyloglucans in the non-lignified primary cell walls of different species of monocotyledons have diverse struc- tures, with widely varying proportions of oligosaccharide units that contain fucosylated side chains （F side chains）. To determine whether fucosylated xyloglucans occur in all non-lignified walls in a range of monocotyledon species, we used immunofluorescence microscopy with the monoclonal antibody CCRC-m1. The epitope of this antibody, α-L-FUCp-（1 →2）- β-D-Galp, occurs in F side chains. In most non-commelinid monocotyledons, the epitope was found in all non-lignified walls. A similar distribution was found in the palm Phoenix canariensis, which is a member of the basal commelinid order Arecales. However, in the other commelinid orders Zingiberales, Commelinales, and Poales, the occurrence of the epitope was restricted, sometimes occurring in only the phloem walls, but often also in walls of other cell types including stomatal guard and subsidiary cells and raphide idioblasts. No epitope was found in the walls of the commelinids Tradescantia virginiana （Commelinaceae, Commelinales） and Zea mays （Poaceae, Poales）, but it occurred in the phloem walls of two other Poaceae species, Lolium multiflorum and L. perenne. The distribution of the epitope is discussed in relation to xyloglucan structures in the different taxa. However, the functional significance of the restricted distributions is unknown.

Cohesive scientific evidence from molecular, animal, and human investigations supports the hypothesis that constitutive overexpression of cyclooxygenase-2(COX-2) is a ubiquitous driver of mammary carcinogenesis, and reciprocally, that COX-2 blockade has strong potential for breast cancer prevention and therapy. Key findings include the following:(1) COX-2 is constitutively expressed throughout breast cancer development and expression intensifies with stage at detection, cancer progression and metastasis;(2) essential features of mammary carcinogenesis(mutagenesis, mitogenesis, angiogenesis, reduced apoptosis, metastasis and immunosuppression) are linked to COX-2-driven prostaglandin E2(PGE-2) biosynthesis;(3) upregulation of COX-2 and PGE-2 expression induces transcription of CYP-19 and aromatase-catalyzed estrogen biosynthesis which stimulates unbridled mitogenesis;(4) extrahe-patic CYP-1B1 in mammary adipose tissue converts paracrine estrogen to carcinogenic quinones with mutagenic impact; and(5) agents that inhibit COX-2 reduce the risk of breast cancer in women without disease and reduce recurrence risk and mortality in women with breast cancer. Recent sharp increases in global breast cancer incidence and mortality are likely driven by chronic inflammation of mammary adipose and upregulation of COX-2 associated with the obesity pandemic. The totality of evidence clearly supports the supposition that mammary carcinogenesis often evolves as a progressive series of highly specific cellular and molecular changes in response to induction of constitutive overexpression of COX-2 and the prostaglandin cascade in the "inflammogenesis of breast cancer".
