When the female is in proestrus, mostly nucleated and some cornified epithelial cells are present. Some leukocytes may be present if the female is in early proestrus. As the stage of the cycle advances to estrus, mostly cornified epithelial cells are present. If the cycle is not interrupted by pregnancy, pseudopregnancy, or other phenomena, metestrus will begin. Metestrus is a brief stage when the corpora lutea form but fail to fully luteinize due to a lack of progesterone. The uterine lining will begin to slough and evidence of this is seen in the form of cornified eipithelial cells and polymorphonuclear leukocytes present in vaginal swabs. Some nucleated epithelia cells will also be present in late metestrus. Diestrus is the longest of the stages lasting more than 2 days. Vaginal swabs during diestrus show primarily polymorphonuclear leukocytes and a few epithelial cells during late diestrus. Leukocytes remain the predominant cell type having removed cellular debris. The cycle then repeats.
Gossypium
These perennial shrubs or small trees are native to tropical and subtropical regions, and are cultivated worldwide for their valuable fiber, which is the primary source of natural textile fibers.
Gossypium species display a diverse range of morphological characteristics, including variation in leaf shape, flower color, and boll (fruit) size and structure.
Understanding the biology and taxonomy of Gossypium is crucial for improving cotton crop yield and quality, as well as developing new textile applications.
Researchers can leverage the power of PubCompare.ai to streamline their Gossypium research, easily locating relevant protocols and identifying the most accurate and reproducible methods to advance their findings.

Although Klason is generally credited as being the first to use sulfuric acid for lignin analysis, Sherrard and Harris (11 ) credit the use of sulfuric acid to Fleschsig in 1883, Ost and Wilkening in 1912, and König and Rump in 1913. According to Harris (12 ), Fleschsig, in 1883, dissolved cotton cellulose and converted it nearly quantitatively into sugars using strong sulfuric acid followed by dilution and heating. According to Browning (13 ), Ost and Wilkening introduced the use of 72 wt % sulfuric acid for lignin determinations in 1910. A translated paper by Heuser (14 ) credited König and Ost and Wilkening for the sulfuric acid lignin method. Dore (15 ) described several improved analytical methods (cellulose, lignin, soluble pentosans, mannan, and galactan) for the summative analysis of coniferous woods. The discrepancies in attribution may be due to differing definitions for the method cited (e.g., first to use acid to determine lignin, first to use sulfuric acid, first to use 72 wt % sulfuric acid, etc.) and to missed citations across continental distances in the early 20th century.

Probe Materials
A number of porous materials were tested to generate charged droplets for mass spectrometry. The materials were shaped into triangles having sharp tips and sample solution was then applied to the constructed probes. Data herein show that any hydrophilic and porous substrate could be used successfully, including cotton swab, textile, plant tissues as well as different papers. The porous network or microchannels of these materials offered enough space to hold liquid and the hydrophilic environment made it possible for liquid transport by capillary action. Hydrophobic and porous substrates could also be used successfully with properly selected hydrophobic solvents.
For further investigation, six kinds of commercialized papers were selected and qualitatively tested to evaluate their capabilities in analyte detection. Filter papers and chromatography paper were made from cellulose, while glass microfiber filter paper was made from glass microfiber.
It was hypothesized that the glass fiber paper was working on mode II and prohibiting efficient droplet generation, due to the relative large thickness (˜2 mm). This hypothesis was proved by using a thin layer peeled from glass fiber paper for cocaine detection. In that case, the intensity of the background increased and a cocaine peak was observed. All filter papers worked well for cocaine detection, (
Probe Shape and Tip Angle
Many different probe shapes were investigated with respect to generating droplets. A preferred shape of the porous material included at least one tip. It was observed that the tip allowed ready formation of a Taylor cone. A probe shape of a triangle was used most often. As shown in

The instant study was designed to test the efficacy in cotton rats of hMPV vaccines against a lethal challenge. mRNA vaccines encoding hMPV fusion protein were used. The mRNA polynucleotide encodes a full-length fusion protein and comprises the wild-type nucleotide sequence obtained from the hMPV A2a strain.
Cotton rats were immunized intramuscularly (IM) at week 0 and week 3 with the mRNA vaccines encoding hMPV fusion protein with either 2 μg or 10 μg doses for each immunization. The animals were then challenged with a lethal dose of hMPV in week 7 post initial immunization via IV, IM or ID. The endpoint was day 13 post infection, death or euthanasia. Viral titers in the noses and lungs of the cotton rats were measured. The results (
Further, the histopathology of the lungs of the cotton mice immunized and challenged showed no pathology associated with vaccine-enhanced disease (

40 grams of zinc bromide was dissolved in 100 ml of 98% formic acid. After 1 hour, all of the salt had dissolved and the solution was heated to 80° C. and hydrogen bromide gas evolved. Once evolution of hydrogen bromide gas ceased, the solution was cooled to 15° C. and 2 grams of cotton, a source of native cellulose with a high degree of polymerisation, was dissolved in the mixture.
Example 14
A 1 L round bottom flask equipped with a condensor was placed under a N2 atmosphere and charged with propylene imine (80.0 gram), n-butyl glycidyl ether (126.0 gram) and K2CO3 (10.00 gram) and heated to 80° C. in 30 min, after which the mixture was stirred for 21 h at T=80° C. After filtration the excess of PI was removed in vacuo, followed by further purification via vacuum distillation, resulting in a colorless low viscous liquid.
1.92 grams of the resulting material (1-butoxy-3-(2-methylaziridin-1-yl)propan-2-ol) was charged to a reaction flask equipped with a thermometer, together with 0.02 grams of bismuth neodecanoate and 19 grams of dimethylformamide. The mixture was stirred with a mechanical upper stirrer under a nitrogen atmosphere and heated to 50° C. A solution of 2.00 grams of Desmodur N 3600 in 19 grams of dimethylformamide was then added dropwise in 45 minutes to the reaction flask, whereafter the mixture was heated further to 70° C. Samples were taken at regular intervals and the reaction progress was monitored using a Bruker Alpha FT-IR spectrometer until no NCO-stretch at 2200-2300 cm−1 was observed. The solvent was removed in vacuo to obtain a clear, yellowish highly viscous liquid. The calculated molecular weight of the theoretical main component was 1065.74 Da, chemical structure is shown below.
Molecular weight was confirmed by Maldi-TOF-MS: Calcd. [M+Na+]=1088.74 Da; Obs. [M+Na+]=1088.76 Da. The following components with a mass below 580 Da were determined by LC-MS and quantified:
Performance of the synthesized compound as a crosslinker was assessed using spot tests on coating surfaces, based on procedures from the DIN 68861-1 standard. For these tests, 0.58 parts of the composition were mixed with 0.60 parts of Proglyde™ DMM (dipropylene glycol dimethyl ether, mixture of isomers) and incubated at 80° C. for 10 minutes under regular agitation. Subsequently, 0.79 parts of the resulting solution were added to 20 parts of NeoRez® R-1005 under continuous stirring, and the resulting mixture was further stirred for 30 minutes. Afterwards, this coating composition was filtered and applied to Leneta test cards using 100 μm wire rod applicators (Test 14-1). For reference, films were also cast from the same composition lacking a crosslinker (Test 14-2). The films were dried for 16 hours at 25° C., then annealed at 50° C. for 1 hour and further dried for 24 hours at 25° C. Subsequently, a piece of cotton wool was soaked in 1:1 EtOH:demineralized water and placed on the film for various timespans. After removal of the EtOH and 60 minutes recovery, the following results were obtained (a score of 1 indicates complete degradation of the film, 10 indicates no damage visible):
