After blood pressure measurement, the rats were anesthetized using isoflurane inhalation and then underwent cesarean section, and the litter weight and number of litters were recorded. The placenta was weighed using an electronic balance (Ohaus, Parsippany, NJ, USA), after which it was immediately placed in liquid nitrogen and stored at -80°C for various biochemical and molecular analyses. The relative placental weight was expressed as [(placental weight/animal weight) × 100].

At 0, 4 and 8 days post-infection, mice were weighed on an electronic balance (Ohaus), sacrificed, and the spleen was removed and weighed on an analytical balance (Sartorius, Göttingen, Germany). The splenic index was calculated as the ratio of the spleen weight and body mass for each mouse.

Daily Mouse Weight Monitoring

+ Expand
Each mouse was weighed daily using an electronic balance (Ohaus, Parsippany, NJ, USA); the weight recorded on the day of infection (day zero) was considered 0%. The percentage of weight variation (PWV) was calculated daily by the following equation: PWV = ((A/B) × 100) − 100, where A is the weight of each mouse on a particular day, and B is the weight on day zero post-infection.

Evaluating Dietary Intake Measurement

The primary outcome measures were energy and macronutrient intake. The amount eaten was determined by weighing to the nearest gram using an electronic balance (OHAUS Corporation, Pine Brook New Jersey) each food item before consumption, then weighing any of the item that was not eaten. A 3-day food diary completed prior to the 9-day test period was analyzed for total energy, protein, carbohydrate and fat content using the NUTRITIONIST Five (version 2.3, 2000, First Data Bank, San Bruno, CA) software.

Quantifying Seed Production in Ephemeral Plants

+ Expand
Most ephemeral plants begin to flower and produce seeds in May. However, seeds fall off easily when they mature, making it difficult to quantify the number of seeds. Therefore, we directly counted the number of capsules per plant before seed maturity (in mid-May), and then multiplied by the number of seeds in the capsule to obtain the total seed production per plant. The seeds were collected after maturity and brought back to the laboratory to dry naturally, where they were weighed in groups of 100 seeds using an electronic balance (Ohaus, NJ, USA), calculated as the hundred-grain weight of the species.

For the electrochemical experiments, differential pulse voltammetry (DPV), adsorptive stripping differential pulse voltammetry (AdSDPV), and cyclic voltammetry (CV) were performed by a PalmSens Potensiostat (Utrecht, The Netherlands) electrochemical analyzer running with PSTrace 5.8 software. The three-electrode cell system comprised a glassy carbon electrode (GCE) with a diameter of 3.0 mm as a working electrode, an Ag/AgCl electrode (3 M KCl) as the reference electrode, and Pt wire as the counter electrode. These were used for the voltammetric analysis of CFT. An electronic balance (Ohaus, Parsippany-Troy Hills, NJ, USA) was used for the precise weighing of the chemicals. A ZEISS EVO 40 (Merlin, Carl Zeiss, Weimar, Germany) was used to acquire the EDX spectra and scanning electron microscopy (SEM) images. A pH meter (Mettler-Toledo pH/ion S220, Greifensee, Switzerland) with an InLab Expert Pro-ISM glass electrode was used for the pH measurement of a buffer solution with an accuracy of ±0.05.

A total of 16 Mg stents were placed into a 1.8 ml cryo-tube filled with artificial nasal mucus (BZ253, BioChemazone, Alberta, Canada) at 37°C, respectively. The artificial nasal mucus was tested in a human ET like environment. The surface morphologies of the Mg stents and mass changes were analyzed at one, two, and four weeks, each with four samples. The remaining four Mg stents were used as a control. The Mg stents were removed from the cryo-tube and washed in an ultrasonic bath immersed in isopropyl alcohol. The mass of the washed stents was measured using an electronic balance (Ohaus Corp., Pine Brook, NJ, USA), and the percentage of mass loss was calculated as follows:
where M and Md were the initial and remaining masses of the stent, respectively [20 (link)]. The surface morphologies of the Mg stents were examined using a scanning electron microscope (SEM, Sigma-300, Carl Zeiss, Germany).

For the analyses of nutrients (proteins, lipids, and carbohydrates), and total phenolic compounds, 30 fruit were immediately processed after arrival from the field. Based on behavioral observations, two oviposited (one for sunny and one for shaded areas) and two non-oviposited (one for sunny and one for shaded areas) mango squares were cut out from each replicate fruit (N = 30) with a dissection knife. Each square was separated by peel and pulp (mesocarp), then chopped, placed on a piece of aluminum foil, weighed using an electronic balance (Ohaus®, Mexico City, Mexico), labeled, immersed in liquid nitrogen, and stored at −80 °C until chemical analyses.

For laboratory reared spiders, body mass and size are correlated [66] . We assessed sexual size dimorphism based on mass and size for spiders reared under the same conditions for a sample of lab-reared spiders. All spiders (N for females, males: L. geometricus = 45, 68; L. hasselti = 42, 72; L. mirabilis = 46, 71; L. mactans = 23, 22; and L. hesperus = 42, 78) were weighed using an analytical balance (Ohaus electronic balance, accurate to 0.01 mg). For the estimation of body size, spiders (N for females, males: L. geometricus = 20, 22; L. hasselti = 21, 20; L. mirabilis = 20, 21; L. mactans = 17, 16; and L. hesperus = 22, 26) were photographed using a dissecting microscope (Zeiss Stemi 2000-C) and a digital camera (Nikon DXM 1200). Photos were taken of the female's and male's patella-tibia length in both left and right front legs, which provides an accurate representation of body size in spiders [47] . The photos were later analyzed and measured using Image J. Sexual dimorphism was calculated as female mass/ male mass, and female size/male size independently. We also report the coefficient of variation for mass and size (CV = standard deviation/mean). This measure of variation can be meaningfully compared across groups with different mean sizes.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
