Advances in the Transformation of Cyclamen persicum Mill. Through Direct Regeneration Based on an Optimized Kanamycin Selection Scheme.

Gene transfer technology has great value in ornamental plants toward the generation of varieties with new ornate characteristics. In the previous studies through the transformation of cyclamen, hygromycin was mainly used as a selective marker. However, there have been some drawbacks associated with hygromycin usage as a selecting agent. Therefore, in the current study, the optimization of kanamycin concentration in the regeneration media has been considered. Subsequently, the plant transformation using three different in vitro explants from three Cyclamen persicum cultivars using three Agrobacterium tumefaciens strains has been examined. Accordingly, the optimal kanamycin concentrations for regeneration from root and leaf explants were determined as 10 mg/L and for microtuber explants as 30 mg/L. The successful gene transformation in the antibiotic-resistant shoots were examined by PCR and UV-equipped microscopes. The gfp reporter gene transfer resulted in the highest efficiency of transformation (60%) to date, from the leaf explants of cv. Pure White inoculated with Agrobacterium tumefaciens strain LBA4404. In contrast, the lowest gene transfer efficiency (25%) was observed in root explants of cv. Dark Violet and cv. Neon Pink inoculated with strains GV3101 and AGL-1, respectively. The results of the current project are expandable to the subsequent investigations of Cyclamen persicum transformation.

Perylene-Based Smart Fluoroprobe with Dual Function: Ratiometric Response toward Hazardous Organic Peroxides and Pure White Light Generation via Self-Assembly.

In this report, we have designed and synthesized a perylene-based smart fluoroprobe (PBE) in which the perylene core has been functionalized with the boronate group at the peri-position. PBE shows a very fast and ratiometric response toward harmful organic peroxides (OPs) generated in old ethereal solvents via auto-oxidation. The response toward OPs takes place with a visible color change from green to yellow, which could be easily observed with the naked eye. The reaction between PBE and OPs involves the cleavage of the boronate group and its consequent conversion into the -OH group. The response of PBE toward OPs was monitored using UV-vis absorption, fluorescence emission, IR spectroscopy, and mass spectrometry. Additionally, we have also explored the self-assembly of PBE in an organic-aqueous solvent mixture, which shows pure white light emission (WLE) with the CIE coordinates (0.33, 0.33) in a 50% dimethyl sulfoxide-water mixture. This work clearly reveals that PBE fluoroprobe can be employed for sensitive detection of hazardous OPs present in old ethereal solvents. Moreover, the ability of PBE to generate the perfect pure WLE makes it a potential candidate for application in organic light-emitting devices.

Effects of substrates and cultivars on growth, yield and flower quality of potted lisianthus [Eustoma grandiflorum (Raf.) Shinners] in Ho Chi Minh City

Lisianthus cultivars are known for their variety of color, size and shape, especially the development of heat tolerant lisianthus for potted ornamentals. The objective of this study was to determine the suitable substrate for good growth and development of some lisianthus cultivars under conditions in Ho Chi Minh City. The two - factor experiment was arranged in a split-plot design with four replications. Factor A (main plot) included three cultivars (Rosita Pink Picotee, Rosita Jade and Rosita Pure White) and factor B (sub-plot) included three substrates (40% coco peat + 60% carbonized rice husk, 40% coco peat + 40% carbonized rice husk + 20% vermicompost và 40% coco peat + 40% carbonized rice husk + 20% cow manure). The results showed that different cultivars of lisianthus significantly affected growth, yield and flower quality. Rosita Jade lisianthus grown on the substrate 40% coco peat + 40% carbonized rice husk + 20% cow manure showed the highest plant height (43.6 cm) and the most number of leaves (43.5 pairs of leaves/plant). Additionally, the application of the substrate 40% coco peat + 40% carbonized rice husk + 20% vermicompost or 40% coco peat + 40% carbonized rice husk + 20% cow manure showed better growth, yield and flower quality of lisianthus compared to 40% coco peat + 60% carbonized rice husk. However, the interaction between cultivar and substrate did not significantly affect lisianthus in terms of number of branches, stem diameter, number of buds, number of flowers, flower diameter and flower longevity.

Pure White Cell Aplasia Associated with Secondary Hemophagocytosis: Experience from the Indus Hospital

Pure white cell aplasia (PWCA), also known as agranulocytosis without granulopoiesis, is an uncommon condition that causes neutropenia. If linked with thymomas or medication-induced PWCA, surgical thymectomy or drug cessation may be therapeutically helpful. Here we present the case of an adult 18-year-old male came at The Indus Hospital and Health Network (IHHN) , Karachi in-patient department (IPD) with a complaint of colicky abdominal pain and loose stools for 10 days that were watery in consistency and large in amount, 6-7 episodes per day, for which he was taking flagyl. 5 days later, the patient developed high grade fever (102°F) with on and off chills that regressed on antipyretic. The patient also had decreased appetite and 2-3 episodes of vomiting. He had a history of dengue fever and Posterior Inferior Cerebellar Artery (PICA).Laboratory work-up revealed that he had been suffering from severe neutropenia. His bone marrow biopsy indicated absolute neutropenia with normocellular bone marrow demonstrating virtually total lack of myeloid progenitors, with maintenance of erythroid and megakaryocytic lineages, findings strongly indicative of PWCA with secondary hemophagocytosis.
 Findings of the case highlights the importance of an unusual clinical condition PWCA with hemophagocytosis. The aggressive clinical course of the idiopathic variant necessitates early immunosuppressive treatment.

Online Survey of Consumer Preferences for Poinsettia Cultivars

New introductions necessitate ongoing studies to keep producers updated about current trends. Consumer preference study results for poinsettia cultivars may interest breeders, wholesale producers, and retail consumers. An online consumer preference survey, conducted from 15 December 2020 to 19 January 2021, was posted in the Qualtrics software platform. Email distribution lists and Facebook were both used to promote the online survey. The survey link was accompanied by a description introducing the project’s purpose and expressing gratitude for participation. Qualtrics automatically collected participants’ data. The survey was closed, and the data were collected on 19 January 2021 from 792 respondents. This study aimed to identify consumer preferences for traditional red, white, or pink poinsettia cultivars and novelty selections. The topmost preferred poinsettia cultivars are “Princettia Queen Pink”, “Winter Rose Dark Red”, “Ice Punch”, “Christmas Mouse”, “Princettia Pure White”, and “Princettia Hot Pink”. The color of poinsettia cultivars did not significantly affect the respondents’ willingness to pay. However, pot size substantially impacted their willingness to pay for poinsettias. Respondents were willing to pay USD 4.89, 8.13, 12.11, and 17.14 per pot for the 4-, 6-, 8-, and 10-inch potted poinsettias, respectively. Some of the socioeconomic characteristics of the respondents influenced their decisions on how much they were willing to pay for poinsettias.

Pure White Bread? Bleached Flour, Contestations, and Regulation in Great Britain, 1900-50.

Why was bleaching-despite early concerns about this new food technology-left unregulated for over half a century? This article focuses on the processes developed to artificially whiten flour in the first half of the twentieth century. It shows how, instead of circumscribing adulteration to practices that they could identify precisely, most scientists in fact foregrounded the limits of their expertise and called for a precautionary approach when dealing with new food technologies and the attendant risks. Setting the British case within a more international context provides a window into the difficulties that regulatory regimes faced, narrowing their definition of adulteration to demonstrably harmful practices. This type of regime led to legitimizing the use of new, potentially dangerous products and processes and made further regulation much more complicated once these technologies became widespread.

Evaluation of mulch practices on growth and yield of four Lisianthus (Eustoma grandiflorum) germplasm

An experiment was conducted in the horticultural farm at Sher-e-Bangla Agricultural University, Dhaka to evaluate the Mulch practices on Growth and yield of four Lisianthus germplasm. The experiment consisted of four treatments (Mo: Control, Ms: Straw mulch, Mc: Cocodust mulch, Mbp: Black polythene mulch) and four Lisianthus germplasms (V1: Arena Type Pure White,V2: Double Pure White, V3: Arena Type Light Pink, V4:Super Magic Type Blue), laid out in a Randomized Complete Block Design (RCBD) with three replications. The results showed significant variations among the four varieties and different mulches. The tallest plant (71.6 cm), thickest stem (5.7 mm) and the largest flower size (70.6 mm) were found in V4 (Super magic type Blue) than others. Plants grown in Black polythene mulch (Mbp) recorded the tallest plant (65.1 cm), highest stem dia. (5.7 mm), maximum stem number (6.4), maximum number of flowers/plant (44.7) and the largest flower size (64.9 mm) than control. Based on the above parameters, the mulches are put in order as follows Mbp ≥ Mc ≥ Ms ≥ Mo. These findings may provide useful data for the improvement of sustainable flower production of Lisianthus.

A Short Review on MicroRNAs on the Proliferation and Apoptosis of Hair Follicle Stem Cells In superior-Pen-Hair Haimen Goat

The superior pen hair, famous for its pure whiteness, brilliant luster and fine elasticity characteristics, is exclusively produced by Yangtze River Delta white goat (Haimen goat) in China. The formation mechanism of the superior pen hair is limited to the role of androgen level and cold stress, which related to certain signals, including CMTM3, Hsp70, and some pathways, such as the Wnt/β-catenin pathway

Seasonal changes in semen characteristics of pure and crossbred rabbit bucks fed graded levels of vitamin C under heat stress conditions

The experiment was carried out to investigate the effect of season and graded vitamin C levels on semen quality of rabbit bucks in the Northern Guinea Savanna of Nigeria. A total of 55 rabbit bucks consisting of 40 pure New Zealand White (NZW) and 15 New Zealand x California (NZW×CAL) crossbreds were used for the study. The duration of the study spanned the hot dry (March-May) and cool wet (June-August) seasons. The traits investigated were semen motility, concentration, volume, pH, colour, live and dead sperm. Results obtained showed that vitamin C had significant (p<0.01) effect on semen characteristics. There was a progressive increase in semen motility, concentration and live sperm and decrease in dead sperm as vitamin C level increased. Semen volume deviated from this pattern while colour was consistent all through. The result on monthly variation indicated that volume increased during the months of March to May ranging between 1.32-1.43 ml while during the months of June to August, it oscillated between 0.41 - 0.95 ml. Sperm concentration significantly (p<0.05) increased from the hot dry months (75.72-129.48x106) to the cool wet months (98.17-102.78x106) while colour remained consistent with an increase in live sperm cells. There was significant (p<0.001) interaction between vitamin C level and season on sperm motility, concentration and live sperm being better in the hot dry (70.9%, 114.5x106, 85.31%) and cool wet (76.3%, 121.6x106, 90.14%) seasons on 400 mg/kg feed vitamin C. Sperm volume was higher on 100 mg/kg feed vitamin C in the hot dry (1.60 ml) and cool wet (0.98 ml) seasons and 400 mg/kg feed in the hot dry (1.57 ml) and cool wet (0.77 ml) than other levels. Based on the results, it is concluded that vitamin C improved the semen characteristics of rabbit bucks at 400 mg/kg feed during the hot dry season which translates to improved semen quality.

Physico-chemical and color parameters to distinguish cow ghee from buffalo ghee.

Ghee production form one of the largest segments of the milk consumption and utilization pattern in India. Recently, cow ghee has become more popular and fetching premium over buffalo ghee as there are innumerable health benefits credit to cow ghee since they contain an important array of nutrients and therapeutic principles. Therefore, the present investigation was conducted to differentiate and characterize cow ghee from buffalo ghee using physico-chemical parameters viz. BR reading, RM value, Polenske value, Kirschner value and different color values. Pure cow and buffalo ghee samples were prepared using creamery butter method. Pure ghee samples (cow and buffalo) and cow ghee samples admixed with buffalo ghee @ 5%, 10%, 15% and 20% were analyzed for above mentioned physico-chemical parameters and different color parameters. The results revealed that BR reading, RM value, Polenske value and Kirschner value of pure cow ghee ranged from 41.87-43.62, 27.5-31.13, 1.30-1.90 and 20.74-24.14 and in buffalo ghee these values ranged from 40.01-43.23, 31.91-39.99, 1.10-1.50 and 26.84-33.96, respectively. The color values i.e. lightness (L), redness(a), yellowness (b), yellowness index (Y) and whiteness index (W) of pure cow ghee ranged from 70.17-81.56, -14.04 to -28.96, 59.68-79.31, 74.25-88.92 and 16.07-28.85 and of buffalo ghee ranged from 71.89-83.71, -1.07 to -11.92, 1.39-9.61, 5.21-22.46 and 68.74-84.61. BR reading, RM value, Polenske value and L, a, b and Y of cow ghee adulterated with buffalo ghee up to 20% falls within the range of different pure cow ghee samples but whiteness index (W) and Kirschner value of admixed cow ghee (23.91 and 34.86) were having significantly higher values than the pure cow ghee (21.07 and 25.45, respectively). Kirschner Value and whiteness index (W) can be used to distinguish cow ghee from buffalo ghee.

Mapping the Regioisomeric Space and Visible Color Range of Purely Organic Dual Emitters with Ultralong Phosphorescence Components: From Violet to Red Towards Pure White Light.

We mapped the entire visible range of the electromagnetic spectrum and achieved white light emission (CIE: 0.31, 0.34) by combining the intrinsic ns‐fluorescence with ultralong ms‐phosphorescence from purely organic dual emitters. We realized small molecular materials showing high photoluminescence quantum yields (ΦL) in the solid state at room temperature, achieved by active exploration of the regioisomeric substitution space. Chromophore stacking‐supported stabilization of triplet excitons with assistance from enhanced intersystem crossing channels in the crystalline state played the primary role for the ultra‐long phosphorescence. This strategy covers the entire visible spectrum, based on organic phosphorescent emitters with versatile regioisomeric substitution patterns, and provides a single molecular source of white light with long lifetime (up to 163.5 ms) for the phosphorescent component, and high overall photoluminescence quantum yields (up to Φ L=20 %).

Pure White Cell Aplasia Complicated by Systemic Sclerosis with Accompanying Scleroderma Renal Crisis

Pure white cell aplasia (PWCA) is a rare neutropenic disorder caused by absence of neutrophil-lineage cells. A 49-year-old man was diagnosed with scleroderma renal crisis 2 months prior to admission to Ohta-Nishinouchi Hospital after experiencing a fever and abdominal pain. Blood tests revealed severe neutropenia, and bone marrow aspirate showed the absence of neutrophil-lineage cells. He was diagnosed with PWCA. Steroids alone were not effective, but adding cyclosporine A and high-dose immunoglobulin recovered his neutropenia and improved his condition. Cyclosporine A and high-dose immunoglobulin are thus considered effective for treating PWCA in autoimmune diseases.

The Influence of Slow-Release Fertilizers on the Growth, Flowering, and the Content of Macro- and Micronutrients in the Leaves of Cyclamen persicum Mill.

The influence of selected fertilizer within a 6-month period of operation was assessed: Basacote Plus 6M, Osmocote Plus 6M, Plantacote Plus 6M. Plants grown in the substrate without slow-release fertilizer, which were supplied with nutrients only for top dressing, were the control. Two cultivars of the Maxi type of cyclamen were grown in greenhouse in pots during the period from the 25th to the 50th week of the year. While planting the seedlings, 2 g of slow-release fertilizer were added to the substrate directly under the roots. From the third week of cultivation, the plants of each combination were fertilized with top dressing every week. Plant height and diameter, number of leaves, weight of the above-ground part, tuber diameter, earliness of flowering, number of flowers and buds, as well as the content of macro and micronutrients were assessed. The addition of Osmocote 6M or Plantacote 6M into the substrate resulted in plants with a larger fresh weight and larger diameter and earlier flowering with more flowers and buds at the end of the experiment than with Basacote 6M or with only top dressing. The applied slow-release fertilizers had an effect on the content of K, Ca, and Fe in the leaves of Persian cyclamen. The cultivar ‘Rainier White F1’ had significantly more leaves, buds, and flowers and a higher content of P, K, Cu, Zn, and Mn than the cultivar ‘Halios Pure White Compact F1’.

EXTERNAL CHARACTERIZATION OF FOUR INDIGENOUS HELMETED GUINEA FOWL VARIETIES (Numida meleagris galeata Pallas 1882) IN NIGERIA

The physical characteristics of 338 indigenous helmeted guinea fowls at 28 and 52 weeks of age were described. Four main colour types or varieties recognised were Ash (Lavender), Black, Pearl (Grey) and pure White. Body weights averaged 1.15 ± 0.03kg and 1.34 ± 0.05kg at 28 and 52 weeks of age respectively for the guinea cocks and 1.07 æ 0.04kg and 1.29 æ 0.06kg at 28 and 52 weeks respectively for the guinea hens. The overall mean body weight for the entire population was 1.1 ± 0.4kg at 28 weeks of age and 1.31 ± 0.07kg at 52 weeks of age. Body weights were significantly (P<.05) bigger at end of laying (52 weeks) than at pointof lay. The males at each age and in each variety also had larger body weights than the females. The guinea cocks had slightly longer body (43.1 vs 42.6cm), keel (14.8 vs 14.4cm), wing (20.3 vs 20.2cm), shank (8.4 vs 7.9cm), drum stick (13.1vs 12.4cm), thigh (9.9 vs 9.6cm), toes and claws, wattle (3.0 vs 2.6cm), jhelmet (3.7 vs 3.2cm), beak (2.7 vs 2.5cm) and larger body girth (30.3 vs 29.4cm) than the guinea hens. About 21.14 and 24.16% of the neck of the males and females respectively were devoid of feathers. Colour of the naked portion of the neck was bluish-black and bear long hair like filoplumes on the dorsalregion. The colour of the beak was light brown in all the birds. All the Black and White birds had light brown shanks while 28.9 and 37.5% of the Ash and Pearl birds, respectively had partly brown and partly grey shank. 62.5 and 28.6% of the Pearl and Ash birds respectively, had brown shanks while 42.6% of the Ash birds had grey shank. The colour of the wattle was red in all the birds. The great variation in the various parameters measured and weighed suggests that they can probably be used in selection and hence genetic improvement of the local helmeted guinea fowl.

All‐Organic, Temporally Pure White Afterglow in Amorphous Films Using Complementary Blue and Greenish‐Yellow Ultralong Room Temperature Phosphors

AbstractOrganic molecules exhibiting afterglow emission (lifetime longer than 0.1 s) under ambient conditions have sparked tremendous attention in recent years as a sustainable energy source with potential applications in displays, lighting, and bioimaging. However, white afterglow organic materials with color purity during the entire period of delayed emission, after the cessation of excitation source, are yet to be achieved due to the different excited state lifetimes of its primary or complementary components. Herein, a remarkable, ambient “temporally pure white afterglow,” which lasts for over 7 s, by coorganizing complementary blue and greenish‐yellow organic room temperature phosphors with similar ultralong lifetimes and efficiency, in an amorphous polymer film is demonstrated. One of the most efficient blue afterglow room temperature phosphors is also reported, with an ultralong lifetime up to 2.26 s and maximum quantum efficiency of 36.8%, from purely organic triazatruxenes en route to the realization of this white afterglow. Further, broad and complementary absorption features of the coorganized phosphors in the visible region facilitates an excitation‐dependent dynamic color‐tuning of the afterglow from sky‐blue to greenish‐yellow.

Synergistic Gelation Effects in Surimi Mixtures Composed of Nemipterus virgatus and Hypophthalmichtys molitrix.

Mixtures of marine fish surimi and freshwater fish surimi might have synergistic gelation effects under certain conditions. Here, various mixtures of Nemipterus virgatus surimi and Hypophthalmichtys molitrix surimi were analyzed, with respect to gelation characteristics, rheological properties, protein conformations, and microstructure. When the ratio of N. virgatus surimi to H. molitrix surimi was 3:1, gel strength was increased by 3.08% and 92.13%, while cooking loss was reduced by 7.64% and 33.94%, as compared to pure N. virgatus surimi and pure H. molitrix surimi, respectively. In the mixed surimi as compared to the pure surimi, brightness and whiteness were improved, while water holding capacity, the elasticity modulus (G'), and the β-sheet content were increased. Three-dimensional (3D) network structure of the mixed surimi gel was more compact and uniform than that of either pure surimi gel. In a word, the elasticity modulus and β-sheet content of mixtures surimi were significantly increased, and the 3D structure was more compact and uniform; all these led to synergistic gelation effects in surimi mixtures composed of N. virgatus and H. molitrix. PRACTICAL APPLICATION: With the accelerated pace of life, the demand quantity of surimi products has increased year by year, but the main raw materials of marine fish resources are increasingly scarce. On the contrary, freshwater fish that can be used for surimi processing resources are very rich, and the price of them is low. Gel properties of freshwater fish surimi is worse than marine fish surimi, and how to improve it is one of the bottlenecks in the development of freshwater fish surimi. We and others have been found that the blended surimi from freshwater fish with marine fish could produce gel synergies under the proper conditions. So, Nemipterus virgatus (marine fish) surimi and Hypophthalmichtys molitrix (freshwater fish) surimi were used as raw materials, and the synergistic effects of the mixed surimi were explored.

Aging Filipino siblings’ interment preferences: application of conjoint analysis

ABSTRACTLike aging, death is inevitable. The loss of a family member is significant to the aging siblings who are tasked with the responsibility of caring for the burial and other funeral services. While there had been studies on funeral services, no research had been conducted on interment services preferences. Hence, the overall purpose of this conjoint analysis study is to ascertain the interment preferences of a select group of aging Filipino siblings. A total of 165 aging Filipino siblings, from two highly-populated provinces in the fifth region of the Philippines, participated in the sorting and ranking of vignettes. Results of the conjoint technique showed the Type of Burial as the most important attribute (22.715%) and Burial Tribute as the least (6.818%). Part-worth of the attributes is: Residence (.158) for Place of Wake; 1 to 3 days (.241) for Length of Wake; Mourning (.536) for the Burial Rituals; Eulogy program (.091) for Burial Tribute; Traditional Burial (1.412) for Type of Burial; Pure White (1.092) for Processional Color Theme; and No obituaries (.161). Marked differences were noted in the female aging siblings giving more importance to the processional/final interment color theme and the obituaries. Also, housewives and the unemployed are inclined to wear pure black during the processional/final interment color theme in contrast to those employed in government agencies. Findings of this study will greatly help in offering not only financial ease but also emotional convenience to the bereaved.

“A Grave of Pure White Snow”: The Documentary Sublime, Environmental Aesthetic, andThe Epic of Everest

As The Epic of Everest (J.B.L. Noel, 1925) begins, a series of ornately scripted title cards offer a prefatory invocation: “Since the beginning of the world men have battled with Nature for the mastery of their physical surroundings. Such is their birthright, and such is their destiny. In this struggle men have now explored tropical forests, polar ice and lofty mountains, sensing the extremities of heat and cold and reaching the ends of the world at either pole. But one great task still remains, THE CONQUEST OF EVEREST—The highest mountain in the world.”
